8u102 NMethod sweeper related Hotspot crashes

Hi guys,

I have a couple of Hotspot crashes to report - both occur in nmethod
sweeping/flushing.  I'm going to strip down the hs_err content, but let me
know if there's something else you need from there.  Are these known? A
quick google suggests there are some bugs around nmethod sweeping, but I
couldn't find anything exactly like this.

Let me know if you need more info.

Thanks
