Robert Muir commented on LUCENE-3869:
-------------------------------------
If you try this seed a lot of times, eventually it will reproduce.
I tried adding -Dtests.iter=10 to my command-line,
so 'ant test -Dtestcase=UIMATypeAwareAnalyzerTest
-Dtests.seed=-262aada3325aa87a:-44863926cf5c87e9:5c8c471d901b98bd
-Dtests.iter=10'
after about 3 or 4 runs it hung... though interestingly it hung at 200% cpu
usage (as if two of the analysis threads were stuck).
Stacktrace is in the same place, just for both threads:

> possible hang in UIMATypeAwareAnalyzerTest
> ------------------------------------------
>
> Key: LUCENE-3869
> URL: https://issues.apache.org/jira/browse/LUCENE-3869
> Project: Lucene - Java
> Issue Type: Bug
> Components: modules/analysis
> Affects Versions: 4.0
> Reporter: Robert Muir
>
> Just testing an unrelated patch, I was hung (with 100% cpu) in
> UIMATypeAwareAnalyzerTest.
> I'll attach stacktrace at the moment of the hang.
> The fact we get a seed in the actual stacktraces for cases like this is
> awesome! Thanks Dawid!
> I don't think it reproduces 100%, but I'll try beasting this seed to see if i
> can reproduce the hang:
> should be 'ant test -Dtestcase=UIMATypeAwareAnalyzerTest
> -Dtests.seed=-262aada3325aa87a:-44863926cf5c87e9:5c8c471d901b98bd'
> from what I can see.
