Does anyone remember the story behind -XX:+UseOldInlining? I have googled, wandered through HotSpot code, searched through JIRA, grepped through Mercurial to no avail. The history on this predates OpenJDK.

In seems we have it unconditionally turned on. It makes the inlining policy a little less understandable to have additional branch here and there. Should we purge this option from the VM codebase? If so, I can prepare the proper revision of this scratch change: http://cr.openjdk.java.net/~shade/scratch/purge-old-inlining.patch

Yes, purge it. It marks a road not taken long ago.
