Dawid Weiss updated LUCENE-4308:
--------------------------------
Attachment: LUCENE-4308.patch
So the problems here are twofold. We should clean up after those unclosed index
writers. The behavior here is correct (two exceptions) because the second
exception is a message indicating the temporary folder (for the unclosed
directory) could not be removed. Not being able to remove a temporary folder is
a bad thing especially on windows where this may affect things down the
execution chain.
The second problem is that the behavior of this loop in _testUtil:
{code}
final Random random = new
Random(RandomizedContext.current().getRandom().nextLong());
do {
result = genTempFile(random, prefix, newSuffix, directory);
} while (!result.createNewFile());
{code}
is different under windows and 1.6/1.7 (J9 and hotspot) -- when a directory
with the given "result" filename already exists 1.6 throws an occasional
IOException and 1.7 returns false.
{code}
Exception in thread "main" java.io.IOException: Access is denied
at java.io.WinNTFileSystem.createFileExclusively(Native Method)
at java.io.File.createNewFile(File.java:883)
at org.apache.lucene.Clazz.main(Clazz.java:25)
{code}
