[8u60] Approval for backport of JDK-8047365

[Hannes Wallnoefer]

Please approve backport of JDK-8047365 to 8u60:

Bug: https://bugs.openjdk.java.net/browse/JDK-8047365
JDK9 webrev: http://cr.openjdk.java.net/~hannesw/8047365/webrev/
JDK8u backport webrev: http://cr.openjdk.java.net/~hannesw/8047365/8u-dev/
Review thread:

I had to merge two changes in MethodEmitter.java manually because of 
later changes in method signature of dynamicGet and dynamicSet. That 
later changes did not touch the code added for this bug however, so the 
merge is very straightforward.

Thanks,
Hannes
