Uwe Schindler commented on LUCENE-5612:
---------------------------------------
The problem is still java at all. You cannot kill a child process easily from
java, and windows is much harder on top. It is just not supported. Jenkins uses
crazy workarounds.
Dawid Weiss' test runners communicate over the file, but thats more hard to do.
Let me think about it.

> I was looking at this, because i wanted to remove the static map inside
> NativeFSLockFactory (no particular reason: it just smells bad, we require
> java7, and you get overlappingexception as of java6 so its unnecessary).
> Before changing any code, i wanted to run lockstresstest first, just to
> ensure it works: but it fails always. Simple works fine always.
> Exception in thread "main" java.lang.RuntimeException:
> java.lang.RuntimeException: lock was double acquired at
> org.apache.lucene.store.VerifyingLockFactory$CheckedLock.verify(VerifyingLockFactory.java:67)
