Subject Re: [JENKINS] Lucene-Solr-tests-only-3.x - Build # 7642 - Failure
Date Mon, 02 May 2011 10:43:38 GMT
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?
