Unfortunately the bit you really need is missing:

#18 0xffff800101aec0a0 in signalHandler (sig=<optimized out>, 
info=0xffff8001026d1fb0, uc=0xffff8001026d1fb0) at 
/srv/openjdk/hs/src/hotspot/os/linux/os_linux.cpp:4396
#19 <signal handler called>
#20 0xffff80010fbfd0c8 in ?? ()
Backtrace stopped: previous frame identical to this frame (corrupt stack?)

It's the original fault that needs to be uncovered. All sorts of 
weirdness can happen in attempting to do error reporting if you were in 
an unexpected state to start with.
