Build: NetBeans IDE 7.3 (Build 201306052037)

OS: Linux

User Comments:
GUEST: Building a maven project

GUEST: I don't know the reason of this exception

GUEST: errr

ejvyas: JUnit with Spring

GUEST: Error root not null

xtecuan: Error al trabajar con GlassFish Server Open Source Edition 3.1.2.2 (build 5) en netbeans 7.3.1

GUEST: Started netbeans and the error shows up

crued: Working with several maven projects, some of which depend on others. Switching back into the source view for the client of the jars produced by the others seems to cause this error.

This seems to prevent other source editing features from working properly, like "Fix Imports." It seems that the IDE is completely unaware of some of the classes contained in the upstream projects.

Unfortunately, I'm not exactly sure how to reproduce. It seems to get better for a little while after clearing out the cache directory under .netbeans, but then re-appears.

It may be nice to skip past this condition to allow source scanning to continue properly, perhaps with reporting the error condition? 

Wish I had more info (maybe the trace has more)

GUEST: project opening

xtecuan: in maven projects

abien: Problem happend during experiments with JBoss 7.1.1 hot deployment

GUEST: new a web filter
