Description Jesse Glick 2003-10-02 01:59:14 UTC 
I am not exactly sure why this is, but JFO.E
threads do not seem to be garbage collected
properly after they die.

Also JCUpdater threads seem to live as zombies.

Try the attached block of code in internal
execution (e.g. paste into Scripting Console under
Dynamic Java). [dev sep 30]

Hint: try to avoid creating Thread's you don't plan to ever start()
(as I see is done in some places with SwingUtilities here).
ThreadGroup seems to have a bug about unstarted threads. Just make a
Runnable and post it instead.

BTW I will escalate:

Comment 5 Miloslav Metelka 2004-01-23 15:20:59 UTC 
This appears to be fixed in tiger-beta but we will try to avoid the
threads that never run anyway into 3.6.

Comment 7 Petr Nejedly 2004-06-14 20:21:10 UTC 
OK, but please keep the relevant attributes and copy cc-ers.
Not only threads are left but it can also cause moderate memory leak.
Comment 8 Miloslav Metelka 2004-07-20 12:53:20 UTC 
Fixed in trunk:
Checking in libsrc/org/netbeans/editor/ext/java/JavaFastOpen.java;
