Yes. I actually ran both 1.7 and 1.8 before replying just to be sure, but since I'm living on the edge here, running the latest builds, the message was in place again. :-)

The message disappeared in 7u4-b18 (HotSpot 23.0-b19) and is back in HotSpot 23.6, not sure which 7u that one will be included in.
