I got NPE when clicking on a server in Servers view. This happens only once after Eclipse starts. Running Eclipse with -clean command line swith didn't help. I'm running 4.2.0.Nightly and updating frequently.

Details from error log:

• message: An internal error occurred during: "Refreshing Process Information".
• stack trace:
  java.lang.NullPointerException
