Comment 2 Andrei Badea 2005-10-26 14:07:04 UTC 
Quite easy. The ProjectManager mutex is hold by APH.putConfigurationFragment()
in EDT and tries to acquire the EJBModules lock. On the other hand the RP thread
holds the EJBModules lock and tries to acquire the PM mutex.

EJBModules.findEjbJar() should not call external code (PM.findProject(), which
aqcuires the PM mutex) from a synchronized block.
Comment 3 Andrei Badea 2005-10-26 14:56:38 UTC 
Hopefully fixed. No way to test, since I've seen the issue only once.

Checking in EJBModules.java;
/cvs/j2ee/ejbfreeform/src/org/netbeans/modules/j2ee/ejbfreeform/EJBModules.java,v
 <--  EJBModules.java
new revision: 1.5; previous revision: 1.4
done

Andrei, can I ask you to look at issue #67595 if it is duplicate of this or not,
please? If it's a dup, i think i'll be able to verify this.
Comment 5 Andrei Badea 2005-10-26 15:49:25 UTC 
Definitely not a duplicate. However, I posted a suggestion how to fix issue
67595 to that issue.
