    [ https://jira.jboss.org/jira/browse/JBAS-6105?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12434615#action_12434615 ] 

Adrian Brock commented on JBAS-6105:
------------------------------------

I've said this many times before.
The BaseClassLoader::defineClass() time is the profiler itself.

When you run the profiler it wil add an agent that modifies the bytecode
That is what is taking the time.

It also has nothing to do with JBCL-49 which is a concurrency issue.
It does not effect how times the defineClass() method occurs.
