I was creating spring-boot project with Activiti.
I noticed that Activiti option is now missing from https://start.spring.io/
for both 1.5.18 and 2.1.1 versions of spring boot.
The Activiti 7 is under development (beta available) with examples on spring-boot 2.x
Can I use Activiti 7 with spring-boot 1.5.18?
For spring boot 1.x you are probably safest to use Activiti 6 as Activiti 7 is being built for spring boot 2.x. But if you're especially interested in Activiti 7 then please feel free to ask on the Activiti 7 gitter chat and discuss your use case with the development team and the community there.

The Problem
We currently have a Spring MVC application (non-spring-boot) based on Spring 5 and Hibernate 5. We have to migrate the app to Hibernate 6.1.
During testing we are encountering exceptions once upgraded to Hibernate 6.1. The root cause exception
java.lang.NoClassDefFoundError:
Could not initialize class org.springframework.orm.hibernate5.LocalSessionFactoryBuilder
Is Spring 5 compatible with Hibernate 6.1? I checked the Spring.io website but could not find any compatibility information for spring-orm.
What I Expected
I expected the application to work with Hibernate 6.1 upgrade.
Environment
Spring MVC 5.3.21 (non-spring-boot)
Hibernate 6.1.0
Tomcat 9.0.64
Java 13
Ubuntu 20
Research Performed
I checked the spring.io website and reference manual. I could not find compatibility information for spring-orm and Hibernate 6.1
How to Reproduce
Deploy a Spring MVC web app (non-spring-boot) that uses Spring 5.3.21 and Hibernate 6.1
We have a lot of spring code written in our AEM application. We are using spring dm to run the code in osgi.
Now we would like to migrate our code to JDK 11 which requires us to migrate spring framework to 5.1 onwards. Is there a spring dm version with support springframework 5.1 onwards.
Are there any other alternative approaches to do such migration ??
regards,
The application is created using spring boot version 1.2.5 Release. I can see that it includes an embedded tomcat version which is 8.0.23. Is it possible to upgrade to a recent tomcat version, let's say, tomcat 9 with spring boot 1.2.5 and still run the application? Or do we need to upgrade the spring boot version to be compatible with tomcat 9? Is there any documentation for the spring boot version compatibility with Tomcat? Thank you.
Why do you want to upgrade it? What is the newer version of tomcat going to bring?
I personally go with the defaults for the spring version unless there is a specific need or issue.
That being said this question may have some pointers
How to change embedded tomcat's version in existing spring boot app?
You may be able to just set the property
9.0.5
It would be preferable to upgrade to the latest Spring Boot release (currently 2.2.5-RELEASE) to avail yourself of the latest features. There are many tutorials, migration guides, problem solutions, etc., out there to guide you, of which here are just a couple:

You didn't specify a reason for keeping your Spring Boot version at 1.2.5-RELEASE and only upgrading tomcat, but if you really must, there are other answers, such as here: How to change embedded tomcat's version in existing spring boot app?
We are currently using the following frameworks and its versions.
Spring Boot parent - 1.4.5.RELEASE
Vaadin-Bom - 7.7.3
Vaadin Spring Boot Starter - 1.1.0
Vaadin-Spring - 1.1.0
Planning to upgrade the spring boot parent version. But i'm sure if we upgrade the spring boot parent version, then need to upgrade the Vaadin dependencies.
I spent few days to find the latest Vaadin frameworks compatibility with the
Spring Boot jars. But couldn't able to arrive at solution. Could you please share your suggestions.
Thanks in Advance!!!
Since Vaadin 7 end-of-life happened already I would suggest migrating to Vaadin 8. You can check the versions in Vaadin 8 full stack app starter with Spring
I am looking to create a new web application using spring boot. Unfortunately my server is fairly locked down in terms of the technology stack. It has java 5 installed on it.
Can anyone tell me whether spring boot can run on java 1.5 and what version?
thanks
Since Spring boot 1.0.0, the minimal requirement to run a Spring boot application has been Java 6. This can also be found in the reference guide of Spring boot 1.0.0:
Spring Boot can be used with “classic” Java development tools or installed as a command line tool. Regardless, you will need Java SDK v1.6 or higher.
Support for older Java versions has been dropped throughout releases, with Spring boot 1.3 moving to Java 7 as a baseline (still possible to use Java 6 with additional configuration) and Spring boot 2.x moving to Java 8 as a baseline. Additionally to what the documentation says, none of the Spring boot 1.x versions support Java 9 or higher.
Summarized:
1.0.0: Support from Java 6 - 8
1.3.0: Support from Java 7 - 8, additional configuration for Java 6 required
2.0.0: Support from Java 8 - ...
So, the answer is that it's not possible to run in Java 5.
For Spring Boot 2.0, the requirement is Java 8 as a minimum version.
From the Spring Boot 2.0 release notes :
Spring Boot 2.0 requires Java 8 as a minimum version. Many existing
APIs have been updated to take advantage of Java 8 features such as:
default methods on interfaces, functional callbacks, and new APIs such
as javax.time. If you are currently using Java 7 or earlier, you’ll
need to upgrade your JDK before you can develop Spring Boot 2.0
applications.
