Hi,

After some internal feedback a new version of the webrev is available at:

http://cr.openjdk.java.net/~jwilhelm/8008790/webrev.hsx24.2/

The biggest change is that the promotion failed event now is sent once per thread instead of merging the info into one event.

Thanks, /Jesper

Hi,

I'm looking for a couple of reviews for the promotion failed tracing event, now implemented for ParNew and Serial GC. I have replaced the existing counters and booleans with a PromotionFailedInfo object and uses that throughout, so now promotion failed reporting (through the tracing framework) looks the same and reports the same data for all young collectors. I have added two new fields to the promotion failed event: firstSize as reported by ParNew logging, and smallestSize which is the smallest object size that failed to promote. Webrew: http://cr.openjdk.java.net/~jwilhelm/8008790 Testing: Passes JPRT and the existing promotion failed tests with all collectors. Thanks, /Jesper
