LockStressTest fails always with NativeFSLockFactory

      Description

      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)

        I added some additional documentation and backported to Lucene 4.8.

        Thanks Robert and Mike for fixing the test and NativeFSLockFactory! I will start the Lucene/Solr 4.8 release candidate tomorrow, once Jenkins is happy.

        I will go to branch 4.x: this doubles our test coverage in flonkings.

        I will leave 4.8 branch alone: you can take care of this release branch. its just merging my branch 4.x commit!

        OK. Do you commit to trunk and I woöll do the rest tomorrow? We should let it bake on trunk first. I will do the complete backport, including adding changes.txt and backport to 4.8.

        Before releasing 4.8, I will see how it behaves on trunk. I hope 4.x does not have additional broken tests

        Uwe, ill let you take care of the note, and Ill just take care of the code, ok?

        If it were up to me, we would not support NFS at all, just throw exception and shut down the JVM completely if you try to use it. Its probably the number one cause of index corruption.

        Hey, all test pass on Windows with tests.directory=*FSDirectory, too!

        We should craefully explain users in the CHANGES.txt or release note that the lock files stay alive. Also for users changing from NativeFSLockFactory to SimpleFSLockFactory (e.g. because they use broken NFS), we should explain that they have to remove the lock file after changing the impl.

        We should also add a comment to the new ant task, so it shows up in core's "ant -projecthelp".

        ok I debugged the rest of the tests with my beast machine over ssh. Separately, we should really look into the speed of these tests (way too slow).

        All tests pass.

        Here is my latest patch, but i am done working on this issue.

        I think the hiding/suppression of output on tests is very bad, we should turn this off and fail tests when they print too much. We should probably stop what we are doing and seriously look at this.

        I'm going to paste my test output for the current fail. Just so you know what I'm dealing with. This is over the top. Tests should not print megabytes of output. I cant even find the failing assertion.
