Thanks.

Some comments:

- g1RemSetSummary.cpp:330:

   out->print_cr("  Concurrent sampling threads times (s)");
   out->print_cr("         %5.2f", service_thread_vtime());

should probably be "Service thread time (s)".

- if you are bored, some copyright dates need updates

- pre-existing: maybe the includes in G1ServiceThread.hpp could be 
fixed; at least runtime/mutex.hpp should be included for Monitor.

Thanks,
   Thomas
