When using JavaSE8u111, we have encountered two jre crashes with Timer.twkFireTimerEvent. its hard to reproduce, but it should be really ensured that jfxwebkit.dll of JavaSE8u111 is crash free even if we can't provide a reproducible test case. If there isn't enough information available in the crash logs, please add more information to the crash logs so that we can prevent these rare but catastrophic errors from crashing the jvm.
