On Metaspace OOM, we log (if Xlog:gc+metaspace+freelist) Information about the chunks used, including waste of chunks in use. The free chunks (chunks lingering in the ChunkManagers) only appear as a total, but it would be helpful to know their number and size by type (medium, small..). This would help to understand OOM better which stem from effects as described here: https://bugs.openjdk.java.net/browse/JDK-8166690.
