Comment 4 Vince Kraemer 2008-11-18 14:40:23 UTC 
this should be easy to fix.
Comment 5 Vince Kraemer 2008-12-11 01:02:29 UTC 
marfous: do you remember whether you had other servers registered in the IDE besides the GF v2 instance... Tomcat? v3?
Something else?
Comment 6 Vince Kraemer 2008-12-12 00:52:52 UTC 
I have not been able to reproduce the exception... so I am doing this change a bit blind....

I am making a change that should make sure that a ServerInstance with a null display name does not end up getting sent
to the comparator...

Log: #152834: try to prevent NPE and provide logging info if a ServerInstance has a null display name
Comment 8 Martin Fousek 2008-12-15 06:21:17 UTC 
It looks to be fixed. Verified with NetBeans IDE Dev (Build 200812141401).
