[jboss-jira] [JBoss JIRA] Closed: (JBAS-8927) jvisualvm on as7 with profile enabled results in ClassCircularityErrors - way to preconfigure AS7 allow it ?

    Resolution: Won't Fix

The best thing to do is add a note to the HackingOnAS7 document, or better yet start a new
"Profiling AS7" wiki page.  Every entry added to that system property slows down

cannot add one specific profiler without adding the others, and we can't really afford
a performance hit across the board for a developer use case.

ClassCircularityErrors - way to preconfigure AS7 allow it ?

                 Key: JBAS-8927
                 URL: https://issues.jboss.org/browse/JBAS-8927
             Project: JBoss Application Server
          Issue Type: Enhancement
      Security Level: Public(Everyone can see) 
            Reporter: Max Rydahl Andersen

 1) start as7
 2) start jvisualvm and connect to the as 7 process.
 3) go to Profiler tab
 4) click CPU
 wait a few seconds and you as7 console output gets filled with ClassCircularityErrors:

 Maybe add -Djboss.modules.system.pkgs=org.netbeans.lib.profiler.server as a default ?
