Description doelf 2011-02-19 02:06:29 UTC 
This bug was originally marked as duplicate of bug 156855, that is already resolved. This bug is still valid, so this seems to be another bug, but it might be related.

Build: NetBeans IDE 7.0 Beta 2 (Build 201102140001)
VM: Java HotSpot(TM) 64-Bit Server VM, 19.0-b09, Java(TM) SE Runtime Environment, 1.6.0_23-b05
OS: Linux

User Comments:
GUEST: when add servers, like glassfish

doelf: Adding an application server is not possible

GUEST: This beta 2 is excellent! I cannot even add a new server. Expanding the branch "Servers" fails, adding a server fails. Shall I restart everything I just installed (5 minutes ago!)

This is same bug over and over again (#194962). The infrastructure won't tolerate null instances returned by ServerInstanceProviders anymore - web-main 132ba9feba7a.

I checked the j2eeserver and it looks quite ok. Vince can you check the glassfish as it is the only other implementation of this SPI?
