Comment 3 David Vancouvering 2008-06-20 17:08:16 UTC 
This seems to be arising fairly frequently - increasing priority.
Comment 4 David Vancouvering 2008-06-20 23:09:07 UTC 
It looks like this happens when we try to remove a connection from the list and it isn't found in the list.  I suspect a
timing issue.
Comment 5 David Vancouvering 2008-06-20 23:55:04 UTC 
I think I know the cause.  It's difficult because I can't reproduce.  I think the problem is I recently changed the
equals() and hashCode() method of DatabaseNodeInfo to make use of the display name. 

The problem is that when you change the URL for a connection, you are changing the display name.  Then later on when you
try to remove the connection, it can't be found in the node list because equals() is returning false when it should be
returning true.

So for a connection we need another way to determine if two ConnectionNodeInfo objects are the same (ConnectionNodeInfo
inherits from DatabaseNodeInfo).

I need to see what other nodes can have their display name changed, or better yet find a hashcode/equals for
DatabaseNodeInfo that relies solely on immutable values.
Comment 6 David Vancouvering 2008-06-20 23:56:25 UTC 
Yes, I was able to reproduce.

- Create a connection
- Disconnect
- Go to properties and change the value for the URL (or username)
- Try to remove the connection

In this way you are guaranteed to get the IllegalStateException

I have a fix.  Will mark this issue as fixed once I push.

David/Honzo,

can you please verify the bugfix in trunk builds? Only verified bugfixes can be ported to NB 6.1 Patch (3) release.

Thanks,

Comment 19 rbalada 2008-07-30 09:42:49 UTC 
The changeset http://hg.netbeans.org/main/rev/37040e6772c5 is not applicable in release61_fixes repository, because it
is effectively a backout of changeset http://hg.netbeans.org/main/rev/18eec35a8c7e made in trunk(6.5) on July 9, 2008
(long after 6.1 branching&release).

I've ported the changeset http://hg.netbeans.org/main/rev/cf2bac824687 into release61_fixes repository as
http://hg.netbeans.org/release61_fixes/rev/52d0c9d1f933
