I am trying toconfigure DCEVM + HotSwapAgent for my eclipse project which uses JDK 7 & JBoss EAP 6.0.

After Replacing DCEVM & adding following VM arguments - I am getting "NoClassDefFoundError: org/jboss/modules/LocalModuleLoader" during JBoss startup.

I tried following steps & encountered different error

  • DCEVM 7u79 installer.jar with latest version of Hotswap agent (1.4.2 jar) and setting VM argument as -XXaltjvm=dcevm -javaagent:<FULL\\WINDOWS\\PATH>hotswap-agent-1.4.2-SNAPSHOT.jar=autoHotswap=true --> I am getting " org/hotswap/agent/HotswapAgent : Unsupported major.minor version 52.0"

  • DCEVM 7u79 installer.jar with Hotswap agent (1.3.0 jar) and setting VM argument as -XXaltjvm=dcevm -javaagent:<FULL\\WINDOWS\\PATH>hotswap-agent-1.4.2-SNAPSHOT.jar=autoHotswap=true --> I was getting "java.lang.ClassNotFoundException: HotswapperPlugin"

  • DCEVM 7u79 installer.jar without Hotswap agent and setting VM argument as -XXaltjvm=dcevm --> I was getting "NoClassDefFoundError: org/jboss/modules/LocalModuleLoader"

  • Uninstalling DCEVM from JDK7 & no VM argument --> starts JBoss without any problem.

Please help me to resolve this error.
