    [JBDS 2.1.1.GA] Package Explorer failing sometimes

    Marc Tille Novice
      Package Explorer is sometimes failling. I am unable to pinpoint to the cause. Sometimes it works, sometimes it does not. 
      The exception is below.

      Environment: OSX 10.6.2, Java 5

      Thank you.



      Here is the exception:
