Subject: Flags are enabled by -XX:+AggressiveOpts

Hello,

My performance tests indicate that using -XX:+AggressiveOpts actually helps my application, but since this flag is marked as experimental I want to be careful with it. I want to know what flags are enabled by -XX:+AggressiveOpts on 1.6u25.

Thanks,
Alexander Livitz
