URL: https://issues.apache.org/jira/browse/UIMA-468
Project: UIMA
Issue Type: Bug
Affects Versions: 2.1
Reporter: Marshall Schor
Assignee: Marshall Schor
Fix For: 2.2
Static variables holding arrays are initialized by seeing if their size is 0
when making a new instance of JCasImpl. If 2 threads do this at the same time,
a race condition could happen.
