Currently Hotspot JVM option "-XX:+PrintGCDetails" does not include one of
the survivor spaces in its output. When we compare the printed out heap usage
to the Xmx setting, this would give a wrong impression that there are still
some heap available for application, while it is actually reserved for one
survivor space and not available for application objects. It would be great
to enhance the option to include all survivor spaces in the output of both
YoungGen and heap.
