Please review - lambda team needs this change to get in by tomorrow so they can push
the (8010433) metafactory change which is waiting on the vm. Thanks.

Testing:
The failure comes if you apply an early patch of 8010433 to the jdk and do not
make the vm change. So testing included 4 binaries: master, newjdk, newvm, newjdkvm
jtreg for SpinedBufferTest with various flags - these are the expected results below
The key point is newjdk -Xverify: all fails
newjdkvm -Xverify:all passes, but if you also turn on -XX:+VerifyLambdaBytecodes you see
the verification error
1. master
no flags: timed out
-Xverify:all: timed out
-XX:+VerifyReflectionBytecodes: VerifyError in reflection
2. newjdk
no flags: timed out
-Xverify:all
java.lang.BootstrapMethodError: call site initialization exception ... cause:
VerifyError: Bad invokespecial instruction: current class isn't assignable to reference class
-XX:+VerifyReflectionBytecodes: VerifyError in reflection
3. newvm
no flags: timed out
rerun.sh: -Xverify:all: passed
-XX:+VerifyReflectionBytecodes: VerifyError in reflection
-XX:+VerifyLambdaBytecodes: passed, didn't try verification
rerun.sh: -Xverify:all -XX:+VerifyLambdaBytecodes: passed
4. newjdkvm
rerun.sh: no flags: passed
rerun.verify.sh: -Xverify:all: passed
rerun.sh: -Xverify:all -XX:+VerifyLambdaBytecodes:
Verification for java.util.streamIntPipeline$7$1$$Lambda$9 failed
regression testing:
newvm:
vm.quick.testlist - in progress
jtreg java/util/stream - in progress
jprt -stree . - in progress
newvmjdk (Brian testing in lambda repo) - in progress
thanks,
Karen
