Comments
I'm backing out the fix for JDK-8225670 due to performance problems. Closing this as duplicate of JDK-8230020.

I've verified that this problem was introduced by the fix for JDK-8225670 but I don't see how that fix could cause the failure. I suspect that it just triggered an existing bug on Sparc (see also JDK-8225620) and will therefore problem list the test. ILW = Unexpected result of stable value with compiled code, single test on Solaris Sparc, -XX:-FoldStableValues = HLM = P3

Needs to be a high priority fix or else ProblemListed due to CI tier3 noise. Please.
