First I compiled Karen's change for 8009130, found this warning, indeed 
there is adding to vmStruct in this changeset, to make clear if this 
caused the warning, I cloned a fresh repo from hotspot-rt and did build, 
the result is same.  From the output, it seems exceeds the default 
setting though we don't know what the value it is.

Thanks
