Summary: The function isn't needed any longer.

I believe the function existed from an earlier day when Metaspace::contains walked the CLDG, so you needed a function to walk the unloaded list as well. Tested with Per's GC test suite and mach5 tier1-5 (until it failed in infra for some platforms), and my own local testing like: jtreg -exclude:open/test/hotspot/jtreg/ProblemList.txt open/test/hotspot/jtreg:hotspotallnoapps

I also ran GCBasher and runThese with -XX:+VerifyBeforeGC -XX:+VerifyDuringGC -XX:+VerifyAfterGC. thanks, Coleen

(and the closed jtreg tests too). open webrev at http://cr.openjdk.java.net/~coleenp/8199007.01/webrev bug link https://bugs.openjdk.java.net/browse/JDK-8199007 Thanks, Coleen
