Resolution:
It looks like the agent has both the fieldpack (new agent mode) and the old delivered agent version is also there (legacy mode). Note the following messages: 1- /usr/wily/introscope10.7/jvmagent/core/ext/ca.apm.fieldpacks.agent.WebSphere Portal Extension.jar". 2- /usr/wily/introscope10.7/jvmagent/core/ext/PowerPackforWebspherePortal_ext.jar". We suggest you to take the second one out: PowerPackforWebspherePortal_ext.jar, as that should really only work in legacy mode. The fieldpack should work good in new mode.
