"Disabling Explicit GC" message in gc log with G1 collector

Hi,

while playing with the G1 collector I noticed that our gc logs are now
filled with a "Disabling Explicit GC" message repeating quite often.

This seems to be coming from g1CollectedHeap.cpp
G1CollectedHeap::do_collection().

We have -XX:+DisableExplicitGC and -Xloggc enabled by default, so in a
way this is pretty much expected. 

I've now removed the print statement there, so that the gc log becomes a
bit more readable. Was there a reason that G1 logs this condition? 

Regards,
