Description David Vancouvering 2008-04-29 06:34:24 UTC 
When I start NB with a fresh userdir, I get an ArrayIndexOutOfBoundsException:

SEVERE [org.openide.util.RequestProcessor]
java.lang.ArrayIndexOutOfBoundsException: 0
	at org.netbeans.modules.db.mysql.DatabaseServerManager.lookupDatabaseServer(DatabaseServerManager.java:64)

See attachment for full stack trace. 

Just before this I get

WARNING [org.openide.loaders.FolderList]: cannot compute data objects for MultiFileObject@afb167[Databases/NodeProviders]

If I run again with the same userdir, the error goes away.

The offending code is indexing into the list of implementations of DatabaseServer returned by lookup.  If you look in
the layer file for db.mysql, there is a registered implementation of DatabaseServer. For some reason it is not found the
first time you run in a clean userdir.  I'm thinking caching...

Comment 2 David Vancouvering 2008-04-29 06:40:34 UTC 
I made this a P2, since you can restart to fix it, but it leaves a nasty first impression, so it would be very good to
fix.

Comment 3 David Vancouvering 2008-04-29 06:47:27 UTC 
FYI, I just tried to reproduce on Windows XP (in a VMWare Fusion VM) and I couldn't reproduce:

Note this was fixed a couple of days ago: this changeset was done on April 30. 

I noticed one report was from the 5/1 build.  Has *anyone* since this since May 1st?

I am pretty sure these are related.  I was doing a lookup in a getDefault() method, which itself does a lookup.  This is
causing race conditions.  Please track 134577 -- I am planning to commit a fix tomorrow morning PST.  

If the fix to 134577 does not solve this, please re-open.  I myself am not able to reproduce.
