https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D209599 --- Comment #16 from Andrew Smith <iamasmith.home@gmail.com> --- The patches attached simply add in SIGSEGV as a possible signal that needs = to be handled as the exception whilst using sun.misc.Unsafe functions. The original implementation had handlers for SIGBUS only and with this chan= ge the handlers now raise the appropriate java exception rather than fatally killing the vm. root@testbuild1:~ # /usr/local/openjdk8/bin/java -cp .
