It's weird - even simple classes fail ... maybe the random dir name we make up
for the test is not random enough on my machine? (It is known for its ability
to pick really interesting seeds for Lucene tests :)).
Perhaps we should have the test method in the dirname, in addition to Random?
I see _TestUtil.getTempDir does this:
{code}
public static File getTempDir(String desc) {
File f = new File(LuceneTestCase.TEMP_DIR, desc + "." + new
Random().nextLong());
LuceneTestCase.registerTempFile(f);
return f;
}
{code}
That's bad no? Shouldn't it use LTC.random? And then we could add that seed to
the print in LTC.afterClass ...?

> Project: Lucene - Java
> Issue Type: Test
> Components: general/test

> I've hit an exception from LTC.afterClass when _TestUtil.rmDir failed (on
> write.lock, as if some test did not release resources). However, I had no
> idea which test caused that (i.e. opened the temp directory and did not
> release resources).
> I think we should do the following:
> * Track in LTC a map from dirName -> StackTraceElement
> * In afterClass if _TestUtil.rmDir fails, print the STE of that particular
> dir, so we know where was this directory created from
> * Make tempDirs private and create accessor method, so that we control the
> inserts to this map (today the Set is updated by LTC, _TestUtils and
> TestBackwards !)
