Please, review the fix for:
bug: http://bugs.sun.com/view_bug.do?bug_id=7187554
jbs: https://jbs.oracle.com/bugs/browse/JDK-7187554
Open webrev:
http://cr.openjdk.java.net/~sspitsyn/webrevs/2013/hotspot/7187554-JVMTI-JSR292.1
Summary:
Restore the appendix argument of a polymorphic intrinsic call
needed for a invokestatic re-execution after JVMTI PopFrame().
Description
When JVMTI's PopFrame removes a frame that was called via a call site
that
takes an appendix and that call site is reexecuted the appendix is not on
the stack anymore because it got removed by the adapter.
This fix is to detect such a case and push the appendix on the stack
again before reexecution.
Testing:
UTE tests - in progress: vm.mlvm.testlist, nsk.jvmti.testlist,
nsk.jdi.testlist
Thanks,
Serguei
