Hi,
Original bug:
https://bugs.openjdk.java.net/browse/JDK-8264640
https://github.com/openjdk/jdk13u-dev/commit/efc81a3d
Please review a backport of the fix for CMS. The issue originally manifested in
8u. Original patch applied almost cleanly, except adjustments for very minor
context differences (obj->mark vs obj->mark_raw).
8u webrev:
http://cr.openjdk.java.net/~akozlov/8264640/8.webrev/
Testing: x86_64 build, hotspot tier1 (2 test failures before and after this patch)
Thanks,
Anton
