Betreff: question of ParNewGeneration::real_forwardee_slow

hi all:
I run 100  threads performance test,  use perf top display:

  71.13%  libjvm.so                [.] ParNewGeneration::real_forwardee_slow

ParNewGeneration::real_forwardee_slow waste some CPU time. I search  google

ParNewGeneration::real_forwardee_slow belong of  parNewGeneration.cpp, also is JDK bug: https://bugs.openjdk.java.net/browse/JDK-7171273.  replaced to G1?

Thanks!
