Robert Muir updated LUCENE-4252:
--------------------------------
Attachment: LUCENE-4252.patch
heres the update patch, it just doesnt do the part before, and looks at the
static fields at the end.
we dont care how they were initialized, we dont want them hogging up RAM!
> Detect/Fail tests when they leak RAM in static fields

>
> We run our junit tests without firing up a JVM each time.
> But some tests initialize lots of stuff in @BeforeClass and don't properly
> null it out in an @AfterClass, which can cause a subsequent test in the same
> JVM to OOM, which is difficult to debug.
> Inspiration for this was me committing Mike's cool TestPostingsFormat, which
> forgot to do this: then we were seeing OOMs in several jenkins runs.
> We should try to detect these leaks in LuceneTestCase with RAMUsageEstimator
> and fail the test.
