> There was a race condition reported when running Pig in local mode on the user mailing
list. This motivated me to fix potential multithreading bugs that can be identified by FindBugs.
> FindBugs identifies the following potential bugs:
> # Mutable static field
> # Inconsistent synchronization
> # Incorrect lazy initialization of static field
> # Incorrect lazy initialization and update of static field
> # Unsynchronized get method, synchronized set method
> There are in total 1153 warnings that FindBugs complains, but they're outside of the
scope of this jira.
