Resolution: Fixed
> test case for JCasHashMap multi-threaded not reliable
> -----------------------------------------------------
>
> Key: UIMA-3992
> URL: https://issues.apache.org/jira/browse/UIMA-3992
> Project: UIMA
> Issue Type: Improvement
> Components: Core Java Framework
> Affects Versions: 2.6.0SDK
> Reporter: Marshall Schor
> Assignee: Marshall Schor
> Priority: Minor
> Fix For: 2.6.1SDK
>
>
> There is a test in the JCasHashMapTest which runs multiple threads, and
> depends on sub threads running ahead of the main thread, but it uses sleep
> delays to attempt to achieve that. This is not reliable, in case the whole
> Java process is pre-empted for longer than the longer sleep. Change this to
> use, in addition, thread priorities - making the main thread have a lower
> priority than the sub-threads, so if the wait times are both expired, still
> the sub-thread runs before the main test thread.
