Description

As part of testing Lucene-4069 I have encountered sporadic issues with files going missing. I believe this is a bug in the test framework (multi-threading issues in MockDirectoryWrapper?) so have raised a separate issue with simplified test PostingFormat class here.
Using this test PF will fail due to a missing file roughly one in four times of executing this test:
ant test-core -Dtestcase=TestIndexWriterCommit -Dtests.method=testCommitThreadSafety -Dtests.seed=EA320250471B75AE -Dtests.slow=true -Dtests.postingsformat=TestNonCoreDummyPostingsFormat -Dtests.locale=no -Dtests.timezone=Europe/Belfast -Dtests.file.encoding=UTF-8
