Is "-XX:G1OldCSetRegionLiveThresholdPercent" a flag in java 7?

[Jesper Wilhelmsson]

Hi Ryan,

-XX:G1OldCSetRegionLiveThresholdPercent has been replaced by 
-XX:G1MixedGCLiveThresholdPercent

It is also an experimental option which means you should only use it if you know 
what you are doing. To enable experimental options use 
-XX:+UnlockExperimentalVMOptions as shown in some of the examples in the 
presentation.

Hth,
/Jesper
