Description ehucka 2006-05-10 11:00:10 UTC 
NB 5.5 beta

I have no steps to reproduce. I worked on a web project and I invoked Go to
Class action - it contained wait... message.

Comment 2 Pavel Buzek 2006-06-15 01:42:07 UTC 
It looks like the problem is in the 2 threads started in
org.netbeans.modules.j2ee.metadata.NNMDRListener$3.run(NNMDRListener.java:191)

They both lock on ClassPath.getRoots and then they wait on each other in
org.netbeans.api.java.classpath.ClassPath$RootsListener.fileFolderCreated(ClassPath.java:757)

Not sure if this is a wrong usage pattern in NNModelerListener or a problem in
CP API. 

Tomasi can you comment? Thanks.
Comment 3 Tomas Zezula 2006-06-19 20:02:44 UTC 
The ClassPath.getRoots() is fixed in trunk to not to call SPI code in
synchronized block. See issue: #77209. I will integrate it to 5.5.
