Dawid Weiss commented on LUCENE-4083:
-------------------------------------
Just a comment on the belated follow-up check that I did. If the main test's
thread times out, any forked threads will also be interrupted/ terminated as a
consequence of this. Any exceptions that happen after the main thread is
terminated will be wrapped as in here (note "after termination attempt").
{code}
java.lang.RuntimeException: Thread threw an uncaught exception (after
termination attempt), thread: Thread[spinning,5,]
at
com.carrotsearch.randomizedtesting.RunnerThreadGroup.processUncaught(RunnerThreadGroup.java:97)
at
com.carrotsearch.randomizedtesting.RandomizedRunner.runSingleTest(RandomizedRunner.java:857)
at
com.carrotsearch.randomizedtesting.RandomizedRunner.access$7(RandomizedRunner.java:804)
at
com.carrotsearch.randomizedtesting.RandomizedRunner$3$1.run(RandomizedRunner.java:671)
at java.lang.Thread.run(Thread.java:662)
Caused by: java.lang.RuntimeException: foobar
at __randomizedtesting.SeedInfo.seed([54B0307E3EA5B518]:0)
at
com.carrotsearch.randomizedtesting.TestTestTimeoutAndRunawayThreadException$Nested$1.run(TestTestTimeoutAndRunawayThreadException.java:22)
{code}
So I don't think the above exception was a result of after-the-timeout
exception, rather something else.

> Key: LUCENE-4083
> URL: https://issues.apache.org/jira/browse/LUCENE-4083
> Project: Lucene - Java
> Issue Type: Bug
> Components: core/store
> Affects Versions: 4.0
> Reporter: Andrzej Bialecki
> Fix For: 4.0
>
>
> The while() loop in RateLimiter.pause() invokes Thread.sleep() with
> potentially large values, which occasionally results in InterruptedException
> being thrown from Thread.sleep(). This is wrapped in an unchecked
> ThreadInterruptedException and re-thrown, and results in high-level errors
> like this:

> I believe this is a bug - the while() loop already ensures that the total
> time spent in pause() is correct even if InterruptedException-s are thrown,
> so they should not be re-thrown.
> The patch is trivial - simply don't re-throw.
