-verbose:gc output has changed from 1.3 to 1.4 such that when one now gets
a Full GC it may be tagged as "GC" in the -verbose:gc output instead of
"Full GC". This is in the default collectors.

With the Train collector, there is an additional problem with the
following:
when you're running with the train under Merlin, you'll sometimes see
       "Train MSC" (I think that's the string). That's really a "Full"; the
       train has bailed out to MarkSweep for a full-heap GC
