Navina Ramesh commented on SAMZA-625:
-------------------------------------

Actually, I am having trouble running this tools with a sample program. Since 
you are re-using the TaskStorageManager, when you call stop(), it tries to 
create a checksum with the newest offset. In this case, the newestOffset 
happens to be null :( i think you should add a check for that.
