You can't reproduce them easily. That is the nature of such bugs. When i see the crashes, i generally try to confirm its not a lucene bug. E.g. ill run it a thousand times with/without g1 and if only g1 fails, i move on with life. There just isnt time. Occasionally G1 frustrates me enough, ill go and open an issue, like this one: https://issues.apache.org/jira/browse/LUCENE-6098 Thats a perfect example of what these bugs look like, horribly scary failures that can cause bad things, and reproduce like 1/1000 times with G1, essentially impossible to debug. They happen quite often in our various jenkins servers, on both 32-bit and 64-bit, and even with the most recent (e.g. 1.8.0_25 or 1.8.0_40-ea) jvms. --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
