Description

[junit] Testcase: testReadAfterClose(org.apache.lucene.index.TestCompoundFile): FAILED
[junit] expected readByte() to throw exception
[junit] junit.framework.AssertionFailedError: expected readByte() to throw exception
[junit] at org.apache.lucene.index.TestCompoundFile.demo_FSIndexInputBug(TestCompoundFile.java:345)
[junit] at org.apache.lucene.index.TestCompoundFile.testReadAfterClose(TestCompoundFile.java:313)
[junit] at org.apache.lucene.util.LuceneTestCase.runTest(LuceneTestCase.java:88)

This one is a non-bug, if you ask me. The test should fail on SimpleFSD, but on my system FSD.open() creates MMapD and that one cannot be closed, so the read succeeds.

This one suceeds sometimes, sometimes (mostly) fails. Is obviously linked with switch to MMapD, but what is the real cause - I don't know.

Broken assumptions.
