RFR 8019389: SA-JDI JSR292: sun.jvm.hotspot.jdi.StackFrame.thisObject() throws sun.jvm.hotspot.utilities.AssertionFailure: sanity check

[Olivier Lagneau]

Please review the following simple fix.

Issue: https://bugs.openjdk.java.net/browse/JDK-8019389
Webrev: http://cr.openjdk.java.net/~olagneau/8019389/webrev.00/ 
<http://cr.openjdk.java.net/%7Eolagneau/8019389/webrev.00/>

The issue is due to the fact that _invokeHandle bytecode is generated by 
hotspot,
but is not declared in agent code. Just declaring the new bytecode 
solves the assertion failure.

However the tests reported in 8019389 
(bootstrapOtherStratumInStackTrace, targetOtherStratumInStackTrace)
suffer the problem from JDK-7016268 
<https://bugs.openjdk.java.net/browse/JDK-7016268> : Can't get strata 
information through SA-JDI
Thus, the "stratum mismatch" related to JDK-7016268 will still be 
present after fix.
This second problem has to be fixed through JDK-7016268.

Thanks,
Olivier.
