Looks good. I have built the hs repo with these patches and run jtreg on x86, arm64 and arm32. Here is a summary of the results.

x86:

hotspot: passed: 1,372; failed: 30; error: 55
langtools: 3,773; failed: 12; error: 9
jdk: passed: 6,378; failed: 202; error: 10

arm64:

hotspot: passed: 1,315; failed: 31; error: 49
langtools: 3,772; failed: 10; error: 10
jdk: passed: 6,433; failed: 148; error: 8

arm32:

hotspot: 1,212; failed: 50; error: 48
langtools: passed: 3,771; failed: 14; error: 9
jdk: passed: 6,043; failed: 442; error: 18

There were no failures due to fatal errors (ie, SEGV, ABORT, assert/guarantee failure etc).

Currently running jcstress, results in approx 10 hours.

All the best,
Ed.
