java.lang.NoClassDefFoundError: org/netbeans/lib/profiler/server/ProfilerRuntimeCPUFullInstr

Complete instructions for running VisualVM against JBoss EAP 6.2.0 GA and JDK 1.7.0_80 are a little thin.

In NetBeans issue 214401, @thurka mentions:

You need to modify JBoss startup arguments. JBoss has to be started with "-Djboss.modules.system.pkgs=org.jboss.byteman,org.netbeans.lib.profiler.server" system property.

Others have mentioned similar parameters:

-Djboss.modules.system.pkgs=org.netbeans.lib.profiler.server -Dorg.osgi.framework.bootdelegation=org.netbeans.lib.profiler.server,org.netbeans.lib.profiler.server.*

The ProfilerRuntimeCPUFullInstr class can be found within %JAVA_HOME%\lib\visualvm\profiler\lib\jfluid-server.jar, which is the version that must be run by JBoss. Without additional configuration, it seems unlikely that JBoss can find the class.

The file domain.bat has been changed to include:

set "JAVA_OPTS=%JAVA_OPTS% -Djboss.modules.system.pkgs=org.jboss.byteman,org.netbeans.lib.profiler.server"

Yet this change alone is insufficient. There are a number of ways to configure domain.bat so that the JBoss JVM, when started, can find the class that won't work:

• Set CLASSPATH or JBOSS_CLASSPATH.
• Use the -cp or --classpath parameter.
• Create a custom module.

How can JBoss be configured to find ProfilerRuntimeCPUFullInstr, tucked away inside jfluid-server.jar?

So what is wrong with

set "JAVA_OPTS=%JAVA_OPTS% -Djboss.modules.system.pkgs=org.jboss.byteman,org.netbeans.lib.profiler.server”
