We don't rely upon GC to cleanup mappedbytebuffers, we unmap them explicitly on close in lucene. But the JDK has crazy loops with explicit GCs in exceptional cases to try to force unmapping. In general we don't want any of our code or library code calling this method: so its banned in forbidden-apis as well.
