      Description

      The GCTraceTime timer that is intended to measure class unloading time in the parallel compact gc code (psParallelCompact.cpp, line 2414ff) spans class unloading, symbol and string table processing.

      Other GCs break that out in separate timings, and parallel compact should do that too.

      ILW: L (only timing), M (only occurs when printing timing), H (no workaround) -> P4
