Description _ pcw 2005-11-21 18:21:46 UTC 
I was attempting to create some CMP Entity beans (against AS 8.1, Pointbase, if
that matters) and the wizard hung or deadlocked or something when connecting to
the DB.  The connection code is executed in the AWT thread (bad!) so the whole
IDE is dead now.

Thread dump attached.

Comment 2 Andrei Badea 2005-12-01 14:51:20 UTC 
It's not a deadlock by definition. There is a JDBC call in the AWT thread which
makes it wait for input from a network socket. 

Should not make JDBC calls in the AWT thread.
Comment 3 Andrei Badea 2005-12-07 20:50:31 UTC 
Fixed. The JDBC calls are now made in a request processor and a progress dialog
is displayed.
