Description
JDK-8140597 disallowed initial mark in the last young-only gc to avoid requests to start initial mark not start any mixed gcs. That restriction could be lifted slightly, if in the coming mixed gcs there is nothing to do (no candidate regions), allow G1 to start an initial mark (and skip the last young-only gc).
