Description

Under some allocation patterns, MarkCompact can GC successfully without ever reporting that it successfully allocates. This is due to the way it (presently) reuses allocated blocks without returning them to the underlying page resource. After 10 GCs, a sanity check is triggered and MMTk dies.
