We have a javaagent written in Java 8 that instruments application code using javassist. There is one simple ClassFileTransformer that instruments java.lang.Error class constructor to record an instantiated error. I am retransforming Error class because it is loaded much before my agent is loaded. The instrumetation code used links java.lang.Error class to classes in agent jar. As java.lang.Error is loaded by bootstrap class loader and that Error is linked to classes in agent jar, I am using -Xbootclasspath/a option to load agent classes as well using bootstrap class loader. This is working fine in Java 8.
Now to Java 9+: Now I am trying to run the same Java 8 agent in Java 9 JVM and running into modularity issues. I am still using -Xbootclasspath/a option because I still have to load the agent classes using bootstrap class loader. As with Java 9 modularity, my agent classes are loaded into unnamed module of bootstrap class loader. Though java.lang.Error class is also loaded by bootstrap class loader but it is part of java.base named module in Java 9 and I am running into below error because unnamed module is not accessible to named java.base module.
Java command line options used are -Xbootclasspath/a:"path-to-agent.jar" and -javaagent:path-to-agent.jar

So after some googling I found there are java command line options to overcome these issues. Accordingly, now I am using these below command line options
1) -Xbootclasspath/a:"path-to-agent.jar"
2) -javaagent:path-to-agent.jar
3) --module-path path-to-agent-jar-folder
4) --add-modules sg.agent
5) --add-modules java.base
6) --add-reads java.base=sg.agent
and agent jar file has below contents in it's manifest file.
Manifest-Version: 1.0
Premain-Class: com.sg.agent.SGAgent
Can-Retransform-Classes: true
Created-By: Srinivas
Automatic-Module-Name: sg.agent
Add-Exports: module/package
Add-Opens: module/package
Boot-Class-Path: C:/Test/SGAgent.jar
and now JVM is throwing below error. From the below stacktrace it can be seen that JVM has read sg.agent as a named module but still complaining no such class: com.sg.agent.ErrorRecorder though --add-reads option gives java.base access to sg.agent. And additionally, my jetty server is not starting now.

I am unable to figure out why this is happening. I even changed the JAVA version to 8 on my system, but the error persists.
I know I'm too late but here's the solution that worked for me in Intellij for the same problem:
Please add "--add-opens java. Base/java.net=ALL-UNNAMED" to your VM option.
For intellij : Open Run/debug Configurations > Create an application for your file if its already not there > Add VM Option > add this config in VM "--add-opens java. Base/java.net=ALL-UNNAMED"
I have setup a customer authorizer by setting below properties in server.properties
authorizer.class.name= {package_name}.myAuthorizer
And myAuthorizer.java implements from kafka.security.auth.Authorizer
And included the myAuthorizer.jar in the libs directory.
It is working as expected but I am wondering if I can include the application properties using Dependency Injection.
I have tried to migrate the current working myAuthorizer to Spring project and running on the IDE is successful, but in the broker I am getting this exception:
java.lang.ClassNotFoundException: {package_name}.myAuthorizer

For the custom Authorizer, can I build as Spring Java project? Or should I leave it as Java project?
I get a NoClassDefFoundError when trying to add a dependency to my custom Gradle plugin, and I haven't found a way to solve it.
Added to the plugin's dependency block:
implementation("org.apache.logging.log4j:log4j-api:2.11.2")
implementation("org.apache.logging.log4j:log4j-core:2.11.2")
Added to the plugin's DeclarationAttributeAltererExtension implementation:

The full implementation and test case is in a separate branch at https://github.com/henrik242/kotlin-really-allopen/tree/unable-to-add-dependencies
Recreate the problem by running ./gradlew clean :kotlin-really-allopen:build :kotlin-really-allopen:publishToMavenLocal :functional-test:build
I suspect your problem is because of known classloader issues with plugins exercised with Gradle's TestKit.
I will paraphrase what that link says: Your plugin and its runtime classpath are loaded with one classloader. The functional test and its classpath are loaded in yet a second different classloader. Such a situation is the classic recipe for NoClassDefFoundErrors. Therefore, when using TestKit with a custom plugin, the plugin's runtime classpath must be explicitly injected into the runtime classpath of the functional test that is exercising the plugin.
The way your project is organized — with the functional test as a subproject — is likely to compound those known classloader issues. It certainly makes things more complicated than they need to be.
The answer to your question, therefore, is: Reorganize your project.
Using the Gradle User Guide as a guide, I simplified your project.
I forked and reorganized it the way Gradle advises.
The fixed code is in the able-to-add-dependencies branch of the fork.

It happens when you have multiple versions of jars added in your maven dependency(mismatch of jar versions),
*Caused by: java.lang.VerifyError: class * so check your maven dependency.
for spring you can find all the dependencies here
for hibernate you can find all the dependencies here
for struts you can find all the dependencies here
