nope, no plans to work on this given the impl is different in 0.23

> 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.
