> 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
