Request for review: 8008546: G1: Wrong G1CONFIDENCEPERCENT results in GUARANTEE(VARIANCE() > -1.0) FAILED

[vladimir kempik]

Hi all,

Could I have a couple of reviews for this change?

http://cr.openjdk.java.net/~mcherkas/vladimir/8008546/webrev.00/

Input value for G1CONFIDENCEPERCENT wasn't checked before using. This results in crash sometimes if -XX:+UseG1GC -XX:G1ConfidencePercent=200 flags are used. Now checking the value same way as it was done for G1ReservePercent. Increase to 0 if negative, decrease to 100 if more than 100.

Thanks,
Vladimir
