I am trying to add a javaagent to my bluemix app, this agent uses Instrumentation. The thing is that when I run the application I get the following error:
premain() - Instrumentation is already running
...
CWWKF0004E: An unknown exception occurred while installing or removing features. Exception: java.lang.NoClassDefFoundError: agent.ClassInstrumentorTransform
ERR at com.ibm.ws.kernel.feature.internal.subsystem.SubsystemFeatureDefinitionImpl.setHeader(SubsystemFeatureDefinitionImpl.java)
ERR at [internal classes]
I have tried creating another agent with the same Premain-Class and Agent-Class structure but with my own classes and it works, I have tried uploading my own copy of Instrumentation classes and point the javaagent to it using Class-Path but the error still appears.
Any sugestion what can be the problem?
I suspect maybe the Bluemix enviorment uses the Instrumentation, any ideas how this might be checked and how I can solve the inter dependency?
Based on the error message, it looks like you have a class in a feature bundle that is trying to access a class from the javaagent, but you have not added the javaagent package to org.osgi.framework.bootdelegation as described in the Specifying Liberty profile bootstrap properties" topic in the knowledge center topic.
I am working on a tomcat web app (tomcat 5.5.30) which consists of GWT widgets (GWT 1.7.0).
While running the ant build, the compilation fails with following error:
...
ERROR] Unexpected internal compiler error
[java] java.lang.StackOverflowError
[java] at java.io.ObjectInputStream.defaultReadFields(ObjectInputStream.java:1891)
[java] at java.io.ObjectInputStream.defaultReadObject(ObjectInputStream.java:479)
...
The JDK version I am using is jdk1.5.0_22. Interestingly, the build completes successfully with JDK version 1.5.0_13. I've also tried to build with jdk1.5.0_18, but it fails with same error message.
I searched the web, and found this discussion. I tried the solutions but none works for me.
I am unable to find out, what has changed after jdk1.5.0 update 13 that my build is failing.
Thanks in advance.
