Hi all,

Could I have a couple of reviews for this change?

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.
