I slurped this hprof down and opened it w/ YourKit... Something weird is going on, because there is a single massive (151 MB) string, stack local to one of the threads, filled with character U+00B2. The test itself looks innocuous; I don't think it creates any massive stack local strings. I'm baffled. Robert maybe something crazy is happening in RuleBasedCollator?

Robert maybe something crazy is happening in RuleBasedCollator? thanks for debugging this... at first I think it must be a jre bug just because the test has been toned down so many times. but, this test doesn't oom intermittently in trunk right? So before disabling the test and saying its out of our hands, it would be good to check that its not a bug in the encoder (Indexablebinarystringtools) - To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org

Robert maybe something crazy is happening in RuleBasedCollator? upon further investigation, i think it must be a JRE bug. for one, i cannot (and was never able to) repro this locally. for now i'd like to change the test to use randomSimpleString. hopefully this is enough to dodge the bug! - To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
