Comment 2 Martin Fousek 2010-12-02 08:38:09 UTC

I got perhaps the same exception/issue. What I'm remembering from my steps:
1, I have project under SVN SCM
2, In free-form project:
   - I moved one file WSMTest.java from package B into package A by using d&d and confirmed refractoring
   - Then I worked on the moved class
   - After few minutes I wanted to move from B to A also another file SOATest.java
   - I dragged this file from B and whole IDE crashed by dropping into A (the same package as the WSMTest.java before)

-> Strange on that is that in the messages.log I found out that the exception was caused by WSMTest.java file, but it wasn't the file which I was moving lastly.

When a module was being turned on

Comment 5 Jaroslav Tulach 2010-12-06 10:38:42 UTC

... the content of system filesystem seems inconsistent: org.netbeans.core.startup.layers.ModuleLayeredFileSystem.setURLs

Comment 6 Jaroslav Tulach 2011-06-30 07:41:49 UTC

Michel's report is about SystemFileSystem. Martin, is not. They should not be mixed...

As far as I can tell the original problem has the same symptoms like bug 103159. The FS events are delivered from inside of unload and at that moment the system may not be in sync.
