Hello Chihiro,
The changes in the following webrev look good to me:
http://cr.openjdk.java.net/~dbuck/8181647.0/
A few minor suggestions though:
- src/jdk.hotspot.agent/share/classes/sun/jvm/hotspot/oops/OopUtilities.java
Lines 354 - 370:
Extra whitespace in the if conditions can be removed:
if( status == THREAD_STATUS_NEW ){
to
if(status == THREAD_STATUS_NEW){
please do this for all the 'if' statements.
- share/classes/sun/jvm/hotspot/runtime/JavaThread.java.
Line 482: extra line; can be removed
Line 507: not indented properly
Thanks,
Poonam
