Java tooling bugs go to JDT, not Platform IDE.
Comment 3 Dani Megert CLA 2011-10-17 09:00:24 EDT 
This works fine for me using Juno M2. Can you provide a test case?
Comment 4 Raksha Vasisht CLA 2011-10-24 11:46:35 EDT 
Ping.
Comment 5 Dmitry Vyazelenko CLA 2011-10-25 13:00:51 EDT 
I'm very busy at the moment. Will try to look into test case over weekend!

Please reopen if you have more details.
Comment 7 Deepak Azad CLA 2011-11-08 11:46:56 EST 
Interesting part of the exception

Caused by: java.lang.NullPointerException
    at org.eclipse.jdt.internal.corext.refactoring.structure.MoveStaticMembersProcessor.checkInitialConditions(MoveStaticMembersProcessor.java:334)
    at org.eclipse.ltk.core.refactoring.participants.ProcessorBasedRefactoring.checkInitialConditions(ProcessorBasedRefactoring.java:203)
    at org.eclipse.ltk.core.refactoring.CheckConditionsOperation.run(CheckConditionsOperation.java:83)

However, I don't how we can get an NPE on MoveStaticMembersProcessor.java:334, nor I can reproduce the problem.

Please reopen if you have more details e.g. a code snippet to reproduce the problem.
