Doing this will eventually trigger calling CollectorPolicy::satisfy_failed_metadata_allocation(). Previous to the [8264149](https://bugs.openjdk.java.net/browse/JDK-8264149) fix, this used to trigger an assert. Am I understanding this properly? ------------- PR: https://git.openjdk.java.net/jdk/pull/7554
