Bug#920315: openjdk-11: Please cherry-pick sparc64 optimization patch from openjdk-12
Source: openjdk-11
Version: 11.0.2+9-2
Severity: normal
Tags: patch
User: debian-sparc@lists.debian.org
Usertags: sparc64
Hello!
Recent upstream changes to the openjdk-11 package have resulted in
Zero segfaulting on sparc64. This can be fixed by cherry-pick the
same fix that we are already using in openjdk-12 to address the
issue [1].
Please include the patch from [1] in the next openjdk-11 upload.
Thanks,
Adrian
