This looks to good. I agree with Peter's point about the 2 reads in getInterfaces() although it's unlikely to make a significant difference.

Oh, it can have the difference on non-x86 hardware and/or in optimized code. This nit is fixed here: http://cr.openjdk.java.net/~shade/8016236/webrev.04/

I did the same testing as before: Linux x86_64/release builds and runs jdk/test/java/lang/reflect jtreg successfully; the performance is still there.

If you can create the change-set then I can push this for you today.

Although only Alan counts as official reviewer; do we need another one?

Thanks, -Aleksey.
