Just surprised that more tests aren't impacted. RMI DGC wouldn't work 
with a STW collector if explicit GC were disabled. I haven't heard of 
deployment using it with a concurrent GC but maybe it's okay. I'm just 
surprised that the RMI tests in the jdk repo are robust enough to pass, 
I would have guessed they might need attention (the test group is 
jdk_rmi but it sounds like you might be running those already).
