Environment

Release : 10.7.0

Component : Introscope

Resolution

Make sure that the Startup script has the following entries for the JVM OPTS:

set JAVA_OPTS=%JAVA_OPTS% -javaagent:/CA/Introscope_Agent/Agent.jar -DagentProfile=/CA/Introscope_Agent/core/config/IntroscopeAgent.profile -Dcom.wily.org.apache.commons.logging.Log=com.wily.org.apache.commons.logging.impl.NoOpLog -Dorg.osgi.framework.bootdelegation=com.wily,com.wily.,sun. -Djboss.modules.system.pkgs=org.jboss.byteman,com.wily,com.wily.*

Also, double check If the startup script does not contains duplicated entry like the Jboss module being loaded over below section:

rem # Make Byteman classes visible in all module loaders
rem # This is necessary to inject Byteman rules into AS7 deployments
set "JAVA_OPTS=%JAVA_OPTS% -Djboss.modules.system.pkgs=org.jboss.byteman"

Comment the entry and leave it over JVM_OPTS section only.
