      I saw some java.lang.OutOfMemoryError: Metaspace in our AS-Testsuite runs. Here is a really simple (and clumsy) reproducer for the leak.

      repreduce

      # lower the metaspace size in jboss-eap-7.1/bin/standalone.conf to 
      # -XX:MaxMetaspaceSize=64m
      # start standalone
      ./jboss-eap-7.1/bin/standalone.sh
      # run the following loop (any other mgmt operation should serve the same)
      for i in `seq 1 1000` ; do ./jboss-eap-7.1/bin/jboss-cli.sh -c :read-resource ; done
      # wait for OOM
