I tried using jprofiler to start the dm server. I am getting some ClassDefNotFoundException from the spring core jar. I tried adding the agent.jar into the java 6 profile but still no success. Before I spend too much time investigate this problem, have anyone try it with jprofiler or other profiling tool? I wonder if i need to make the agent.jar as a osgi jar or not. I already start the jvm with agent.jar in the bootclasspath, so all the bundles should have access to it.
