Description stroudcuster 2007-10-25 15:32:51 UTC 
[ BUILD # : Beta 2 ]
[ JDK VERSION : 1.6.0_03 ]

While profiling a Tomcat based web app, I noticed that many classes
are listed twice on the heap class summary display.  I have attached
a screen shot.  The heap file is 39mb, so it's too large to send as
an attachment.  I profiled a very small desktop app (on Linux) and
did not see this behavior.

Comment 2 Jiri Sedlacek 2007-10-30 17:07:43 UTC 
It seems that the duplicated classes are loaded by different classloaders which results in being tracked separately and
displayed twice. To be sure, could you please provide compressed (bzip2 etc.) heapdump (attach here or send via email)?
Comment 3 Tomas Hurka 2007-11-07 10:36:29 UTC 
Changing target milestone to dev, since NetBeans 6.0 is in high resistance mode.
Comment 4 J Bachorik 2008-08-28 10:28:33 UTC 
Closing as invalid. According to the information available those classes were loaded by different classloaders and
therefor are displayed twice.
If you think this is not the case attach the heapdump to this issue (you can use eg. http://rapidshare.com to attach a
bigger heapdump)
