Can someone make sense of the G1 garbage collector output?

Question

I am running a Java program with the G1 garbage collector using the following options:

-XX:-UseBiasedLocking 
-XX:+UnlockExperimentalVMOptions 
-XX:+UseG1GC          


        

Answer 1

I have a tool (pre-release, not OSS yet) which may be able to shed some light here.

If you're interested, please email me and we can talk about how to get the logs to me.

To the comments on the post - I've used G1 in prod-like loads and seen some good numbers (not as good as the ones you're seeing, but better than CMS for some loads).

Haven't seen any crashes from Java 7 betas (but did see some with Java 6 builds).
