Aaron McCurry commented on BLUR-54:
-----------------------------------

I believe the problem may be an uncaught non BlurException, because if a 
BlurException is thrown the client will not retry the call.  If the NPE 
exception is thrown back through thrift on the server-side then a TException is 
thrown to the client and that will cause bad connection / retries to occur.  So 
I think that this is actually 2 problems, one we should provide a better 
exception and two we should not allow non-BlurExceptions to bubble up passed 
the BlurServer api, basically catch everything and wrap in a BlurException (See 
BException as a helper class).
