Spring Integration Flow ClassCastException after Spring Boot 3.0.1 Update - spring-boot

I was working on the Spring Boot Update to 3.0.1 and with it the Upgrade of Spring Integration 6.0.0 and Spring Cloud Stream 4.0.0. After upgrading however my previously working Spring Integration Flow is failing with underlying ClassCastException:
class org.springframework.messaging.handler.HandlerMethod$HandlerMethodParameter cannot be cast to class java.lang.reflect.Type (org.springframework.messaging.handler.HandlerMethod$HandlerMethodParameter is in unnamed module of loader 'app'; java.lang.reflect.Type is in module java.base of loader 'bootstrap')
Update: The exception originates from JsonMessageConverter inside of Spring Cloud Function Context, when trying to cast an object conversionHint (in my case of type HandlerMethodParameter) to Type.
Cannot cast 'org.springframework.messaging.handler.HandlerMethod$HandlerMethodParameter' to 'java.lang.reflect.Type'
Any hints or suggestions as to what might be the problem are highly appreciated.
Following is a highly shortened version of the affected integration flow and corresponding code snippets and a more detailed explanation:
#Bean
IntegrationFlow extract(SessionFactory<SftpClient.DirEntry> sftpSessionFactory,
XmlFileTransformer xmlFileTransformer){
return IntegrationFlow
.from(Sftp.inboundAdapter(sftpSessionFactory)
.preserveTimestamp(true)
.remoteDirectory("foo")
.regexFilter(".*\\.txt$")
.localDirectory(new File("sftp-inbound")), e -> e.id("sftpInboundAdapter")
.autoStartup(true)
.poller(Pollers.fixedDelay(5000))
)
.log(LoggingHandler.Level.DEBUG, "ExtractFlow", m -> "Successfully reached")
.wireTap(MONITORING_FLOW)
.log(LoggingHandler.Level.DEBUG, "ExtractFlow", m -> "Successfully done wire tap")
.transform(xmlFileTransformer)
.log(LoggingHandler.Level.DEBUG, "ExtractFlow", m -> "Successfully done transformation")
.handle(m -> xmlProcessor.process((XmlFile) m.getPayload())
.get();
}
#RequiredArgsConstructor
#Component
public class XmlFileTransformer implements GenericTransformer<Message<File>, XmlFile> {
#Override
public XmlFile transform(Message<File> message) {
return new XmlFile(message.getPayload().toPath(), message.getHeaders().get("x-origin", String.class));
}
}
The Integration Flow from the wiretap again transforms by implementing GenericTransfomer (similary written as XmlFileTransformer and then uses Amqp.outboundAdapter to send messages.
The method xmlProcessor.process takes XmlFile as argument. However it never reaches the actual method because it breaks when trying to go through the wire tap, and in case I comment the wire tap it breaks when trying to transform with xmlFileTransformer. So after log message "Successfully reached" the exception happens.
I'm using following relevant dependencies (other used dependencies not listed for better overview):

I was checking and rechecking my dependencies to ensure that I don't have any old dependencies that might clash with the update. However those should be fine as I'm using mostly the versions from spring-boot-starter-parent.
According to the migration guide of Spring Integration 6.0.0 there shouldn't be any major breaks that I forgot to handle.
I was trying to find any information about similar cases however it seems not too many have either tried to upgrade to Spring Boot 3 yet or just didn't have the same issues as me.
Could this be a bug in Spring Integration or do I need to refactor code so it's still running in Spring Integration 6.0? Or did I overlook issues with my dependencies?

camel springboot and hawtio integration

I am working on integrating the camel springboot component with hawtio. I can't see the camel tab in the hawtio UI. I am using below dependencies of springboot camel and hawtio
<dependency>
<groupId>org.apache.camel.springboot</groupId>
<artifactId>camel-spring-boot-starter</artifactId>
<version>3.2.0</version>
</dependency>
<dependency>
<groupId>io.hawt</groupId>
<artifactId>hawtio-springboot</artifactId>
<version>2.10.1</version>
</dependency>
This the sample route i configured, route is working as expected
#Component
public class SampleRoute extends org.apache.camel.builder.RouteBuilder{
#Override
public void configure() throws Exception {
from("kafka:test123?brokers=localhost:9092&allowManualCommit=true&autoCommitEnable=false&breakOnFirstError=true&maxPollRecords=1&synchronous=true")
.process(exchange -> {
exchange.getIn().setBody("test1234");
}).to("stream:out");
}
}
After reading many articles , i added below set of properties and it seems to have any effect.
management.endpoints.web.exposure.include=hawtio,jolokia
management.endpoints.jolokia.sensitive=false
endpoints.jolokia.sensitive = false
hawtio.authenticationEnabled=false
spring.jmx.enabled=true
camel.springboot.endpoint-runtime-statistics-enabled=true
management.endpoint.camelroutes.enabled=true
management.info.camel.enabled=true
management.endpoint.camelroutes.enabled=true
management.endpoint.camelroutes.read-only=true
camel.springboot.jmx-enabled=true
One of the solution worked for me is by downgrading to camel 2.X , but no luck with camel 3.X
I got it working, following the link as suggested. I had to remove the conflicting dependencies and adding below dependency worked.
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-management</artifactId>
<version>3.2.0</version>

How to resolve NoSuchMethodError in spring TransactionSynchronizationManager.currentTransaction when using pring-data-r2dbc

I am writing service based on Spring webflux, which reads data from PostgreSQL using r2dbc. I need to use latest release of r2dbc, however I am getting NoSuchMethodError exception in using TransactionSynchronizationManager spring-tx 5.2.0.RELEASE library.
I basically need to know what is correct spring-tx library version to be compatible with version of spring-data-r2dbc which works correctly with latest r2dbc-postgresql and r2dbc-spi libraries.
Here are my Maven dependencies.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-webflux</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-r2dbc</artifactId>
<version>1.0.0.M2</version>
</dependency>
<dependency>
<groupId>io.r2dbc</groupId>
<artifactId>r2dbc-postgresql</artifactId>
<version>0.8.0.RC2</version>
</dependency>
<dependency>
<groupId>io.r2dbc</groupId>
<artifactId>r2dbc-spi</artifactId>
<version>0.8.0.M8</version>
</dependency>
I am using interface extending ReactiveCrudRepository interface to retrieve table data per below.
#Query("...")
Flux<QuoteHistory> findAllBySecIdAndDateTimeBetweenAndUpdateTypeIn(LocalDate date, Long secId);
I was able to get this code to work with earlier versions of r2dbc-postgresql and r2dbc-spi but now I am getting following exception.
java.lang.NoSuchMethodError: org.springframework.transaction.reactive.TransactionSynchronizationManager.currentTransaction()Lreactor/core/publisher/Mono;
at org.springframework.data.r2dbc.connectionfactory.ConnectionFactoryUtils.doGetConnection(ConnectionFactoryUtils.java:88) ~[spring-data-r2dbc-1.0.0.M2.jar:1.0.0.M2]
at org.springframework.data.r2dbc.connectionfactory.ConnectionFactoryUtils.getConnection(ConnectionFactoryUtils.java:70) ~[spring-data-r2dbc-1.0.0.M2.jar:1.0.0.M2]
at org.springframework.data.r2dbc.core.DefaultDatabaseClient.getConnection(DefaultDatabaseClient.java:189) ~[spring-data-r2dbc-1.0.0.M2.jar:1.0.0.M2]
These are r2dbc dependencies which code works with.
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-r2dbc</artifactId>
<version>1.0.0.M1</version>
</dependency>
<dependency>
<groupId>io.r2dbc</groupId>
<artifactId>r2dbc-postgresql</artifactId>
<version>1.0.0.M7</version>
</dependency>
Please use the following dependency combination:
R2DBC Postgres: 0.8.0.RC2
R2DBC SPI: 0.8.0.RC2
Spring Data R2DBC: 1.0.0.RC1
Spring Framework: 5.2.0.RELEASE
Alternatively, go to https://start.spring.io to get a dependency-managed project with versions that work together.

incompatible version of apache.camel with Spring.Boot v2.0

Anyone could englighten me which org.apache.camel version I should use with the Spring boot version 2.0.0 .RELEASE.
When I used newer versions of apache.camel such like 2.21.0 , I come across with RelaxedPropertyResolved error. I read the forums and I was told to downgrade the version of Spring Boot which I cant. I have to use sprint.boot.version 2.0.0 with a new apache.camel.version without making changes at my java code ?
Do you think is it possible?
These are my dependecies for camel.version and spring.boot.version. Please let me know if you need anything more.

using embedded amqp swith spring boot and camel

I want to integration test a custom camel component and therefor need an embedded/in memory messanging I can easily use to test from/to endpoints.
I am hoping that I can achieve this via spring-boot-amqp-starter.
I used this example for a start, which has the dependencies:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-activemq</artifactId>
</dependency>
<dependency>
<groupId>org.apache.activemq</groupId>
<artifactId>activemq-broker</artifactId>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
</dependency>
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-spring-boot-starter</artifactId>
</dependency>
and the config:
spring:
activemq:
broker-url: vm://embedded?broker.persistent=false,useShutdownHook=false
// ...
This is working, when I use regular Listener annotations in spring, I have a sender using the template and a consumer logging the messages.
Now I go one step further and use camel, but it does not recognize the vm:embedded broker but tries to connect to tcp://localhost, which is not running.
return new RouteBuilder() {
#Override
public void configure() throws Exception {
from("activemq:foo").to("log:sample");
from("timer:bar").setBody(constant("Hello from Camel")).to("activemq:foo");
}
};
How can I configure activemq-camel to use the embedded broker?
Update:
I use dependency management imports for spring-boot-dependencies (1.5.9)
and camel-spring-boot-dependencies (2.20.1).
This has been fixed in newer versions of activemq-camel when you use that with Spring Boot. Now the activemq-camel component will honor the spring boot configuration of the spring.activemq.* settings.

How to use the latest version of Vaadin4Spring EventBus framework with Maven?

I have a Spring Boot project with Vaadin, I would like to integrate the Vaadin4Spring EventBus framework:
https://github.com/peholmst/vaadin4spring/tree/master/spring-vaadin-eventbus
The author says:
Please note, that the Event Bus API changed in version 0.0.5
However, if I add the Maven dependency inside my pom.xml:
...
<dependency>
<groupId>org.vaadin.spring</groupId>
<artifactId>spring-vaadin-eventbus</artifactId>
<version>LATEST</version>
</dependency>
...
Maven downloads the 0.0.4.RELEASE version. I have tried to explicitly set the following versions:
...
<dependency>
<groupId>org.vaadin.spring</groupId>
<artifactId>spring-vaadin-eventbus</artifactId>
<version>0.0.5</version>
</dependency>
...
...
<dependency>
<groupId>org.vaadin.spring</groupId>
<artifactId>spring-vaadin-eventbus</artifactId>
<version>0.0.5.RELEASE</version>
</dependency>
...
...
<dependency>
<groupId>org.vaadin.spring</groupId>
<artifactId>spring-vaadin-eventbus</artifactId>
<version>0.0.5-SNAPSHOT</version>
</dependency>
...
I also tried to set the entire Spring4Vaadin addon as a dependency:
<dependency>
<groupId>org.vaadin.spring</groupId>
<artifactId>spring-boot-vaadin</artifactId>
<version>LATEST</version>
</dependency>
...
<dependency>
<groupId>org.vaadin.spring</groupId>
<artifactId>spring-boot-vaadin</artifactId>
<version>0.0.5</version>
</dependency>
...
<dependency>
<groupId>org.vaadin.spring</groupId>
<artifactId>spring-boot-vaadin</artifactId>
<version>0.0.5-SNAPSHOT</version>
</dependency>
...
<dependency>
<groupId>org.vaadin.spring</groupId>
<artifactId>spring-boot-vaadin</artifactId>
<version>0.0.5.RELEASE</version>
</dependency>
But neither of them worked.
Basically, I cannot do this:
#Autowired
EventBus.ApplicationEventBUs appEventBus;
#Autowired
EventBus.UIEventBus UIEventBus;
...
Because, as said in the README.md on GitHub:
Please note, that the Event Bus API changed in version 0.0.5. From now
on, you have to declare which event bus to inject by using a specific
interface (previously, everything was EventBus and you used an
annotation to specify which bus to get). The reasons for this change
were
So in the version 0.0.4.RELEASE (which Maven sees as LATEST), the inner interfaces ApplicationEventBus and UIEventBus are not defined.
So, how can I use the true latest version of the addon?
Putting the answer I put in the vaadin forums, over here as well:
Vaadin addons has a nice Event Bus implementation. Check https://github.com/peholmst/vaadin4spring/tree/master/samples/eventbus-sample
I have done this using a spring enabled (NOT spring boot) Vaadin application, but it might work without Spring as well I guess, Short steps:
1. Add the following dependency
<dependency>
<groupId>org.vaadin.spring.addons</groupId>
<artifactId>vaadin-spring-addon-eventbus</artifactId>
<version>0.0.7.RELEASE</version>
</dependency>
Import EventBusConfiguration.class into your Spring configuration (may not be required if Spring Boot is used with #EnableAutoConfiguration)
Wire in appropriate event bus (check doumentations for different types available), here I am using one that works per UI instance:
#Autowired
private EventBus.UIEventBus uiEventBus;
Publish event as required, eg:
uiEventBus.publish(this, new RefreshMainViewEvent(this, "Usage details updated"));
Subscribe to event in the other component class
#PostConstruct
public void afterPropertiesSet() {
uiEventBus.subscribe(this, false);
}
Add the action to be done on event (in the same class here) :
#EventBusListenerMethod
public void closeSymmUsageWindow(RefreshMainViewEvent event) {
logger.debug("Received {}", event);
//blah
}
