Hi, jdk/internal/misc/JavaLangAccess/FormatUnsigned.java started failing after UUID.toString() optimizations purged the methods from JavaLangAccess: https://bugs.openjdk.java.net/browse/JDK-8149044
My bad, I should have ran JavaLangAccess tests after the original change. The fix is to remove the test, because all tested methods are gone now: http://cr.openjdk.java.net/~shade/8149044/webrev.01/ Cheers, -Aleksey
