--- Comment #3 from Jess Holle <jessh@ptc.com> 2010-12-30 09:06:07 EST ---
A very short investigation shows the issue.

1) Tomcat specifies -Djava.io.tmpdir=$CATALINA_BASE/temp in its JVM options.
2) Java 6 Update 23 places the hsperfdata_$USER directory in this directory
rather than in the normal location where jps, visualvm, etc, expect it.

It looks like Oracle needs to either undo this change or provide a means of
decoupling these directories, e.g. a temp dir setting that does *not* change
the hsperfdata location.

I believe this is a bug in Java 6 Update 23.  If hsperfdata is to be placed in
other locations then jps, visualvm, etc, must know how to find it.  This seems
unreasonable, so I'd conclude that the hsperfdata location should not be
impacted by the java.io.tmpdir setting.
