I think this is a bug in RAMDirectory?
I can reproduce with the seed, though i modified the test to actually
deal with exceptions correctly (currently its impossible to tell whats
going on).
If you change the directory to anything else (e.g. MMapDirectory,
SimpleFSDirectory), the test passes.

Here's my patch to the test, so you get a full exception.
