Description _ tboudreau 2008-10-20 22:50:42 UTC 
Components should not be constructed on any thread but the AWT thread.  This is because one of the major sources of
deadlocks in NetBeans is the AWT tree lock.

I added some logging to java.awt.Component and found an enormous number of cases just during startup (possibly safer
then than later, but not strictly safe).

FolderInstance and SharedClassObject are a particularly common roots - probably they should be modified to log a stack
trace if the instance they create turns out to be a Component.  Also, it would be good to log stack traces if assertions
are enabled (bytecode patch java.awt.Component perhaps?)

We are reporting particular issues against particular modules ...
