RFR: 8357662: applications/runthese/RunThese8H.java Crash: 'Failed to uncommit metaspace'

[Coleen Phillimore]

Make the fatal error a log warning and return. The metaspace commit accounting is done after this return.  Tested with this always returning here, and it seems okay.  Tested with this change tier 1-4 and 8.
