      Description

      In JvmManager, when a Jvm exits, it tries to delete the workdir for initalContext.task which is null, hence throwing NPE. Currently this NPE is swallowed into the abyss.

      We should catch exceptions out of the JvmRunner thread, add a test case that verifies this functionality, and fix this code to properly grab the last task.
