Subject: [PATCH] Update runbroker.sh

when use g1 grabage, needen't  set xmn,because it's cause   full gc !

http://www.oracle.com/technetwork/articles/java/g1gc-1984535.html

Young Generation Size: Avoid explicitly setting young generation size with the -Xmn option or any or other related option such as -XX:NewRatio. Fixing the size of the young generation overrides the target pause-time goal.
