Hi,
Please review the following webrev:-
http://cr.openjdk.java.net/~enevill/jdk8u_backports_1605
This backports the changesets listed below from jdk9 to jdk8u.
Tested with jtreg hotspot & langtools. Results the same before and after.
Hotspot: Test results: passed: 682; failed: 17; error: 2
Langtools: Test results: passed: 3,094
No shared code was harmed in the preparation of this webrev!
OK to push?
Ed.
