Description

I found this while testing Storm 1.0.3 RC1, but I think this issue might spot for all version lines.

When testing storm-starter topology with local mode (LocalCluster), after some period it doesn't terminate even shutdown phase ends.

I took thread dump and saw some non-daemon threads are alive at that moment: Async Localizer, Localizer Cache Cleanup. (I'll attach thread dump file.)
