    Description

      Both static and dynamic archive dumping use MetaspaceClosure for copying MetaspaceObjs into an output buffer:

      http://hg.openjdk.java.net/jdk/jdk/file/4d36e29a5410/src/hotspot/share/memory/metaspaceShared.cpp#l1351
      http://hg.openjdk.java.net/jdk/jdk/file/4d36e29a5410/src/hotspot/share/memory/dynamicArchive.cpp#l168

      There's a lot of duplication between the two variants. They should be consolidated.
