Hi all,

JDK-8151674 has been backouted.
However, I want to try to merge this enhancement to hs-rt repos.

I updated testcase in:

  - hotspot/test/serviceability/tmtools/jstat
  - jdk/test/sun/tools/jstat sun/tools/jstatd
      
I ran them with jtreg as below, they works fine.

  - hotspot
      $JT_HOME/bin/jtreg -ignore:quiet serviceability/tmtools/jstat

  - jdk
      $JT_HOME/bin/jtreg -ignore:quiet sun/tools/jstat sun/tools/jstatd


I uploaded a webrev.
Could you review it?

  - hotspot
    http://cr.openjdk.java.net/~ysuenaga/JDK-8153333/webrev.00/hotspot/

  - jdk
    http://cr.openjdk.java.net/~ysuenaga/JDK-8153333/webrev.00/jdk/

Note: I did not modify changes in hotspot and jstat_options in jdk repos.
      Changes from JDK-8151674 is for testcase only.


I cannot access JPRT.
So I need a sponsor.


Thanks,

Yasumasa
