Bug at 3.19-rc3:mm/rmap.c:399

[Jan Engelhardt]

Preliminary report that Linux kernel 3.19-rc3 
[eb74926920cfa756087a82e0b081df837177cb95] gives a bug dump. When 
exiting JOSM (running on openjdk-1.7), the java process would sometimes 
get shot down. Last known good was v3.18.1.

I probably need to turn on some debuginfoâ unless you 
beat me to bisecting it.
