It looks like your patch

http://cr.openjdk.java.net/~aph/jaotc/jdk-hs-1/

didn't apply cleanly to tip of http://hg.openjdk.java.net/jdk/hs

I tried updating to

Summary: gtest vtableStubs introduced by 8174962 fails on AArch64 with an invalid insn encoding
Reviewed-by: duke

Which looks like the rev you are basing your patch on based on the rejected patch.

It seems to get further, but now I get

Is this known/expected? What revision of jdk/hs are you building with? I'd like to see this working.
