This looks like a bug. I can reproduce it on Linux (slowdebug jdk10-hs): # To suppress the following error report, specify this argument # after -XX: or in .hotspotrc: SuppressErrorAt=/os_linux.cpp:4014 # # A fatal error has been detected by the Java Runtime Environment: # # Internal Error (/priv/d031900/openjdk/jdk10-hs/source/hotspot/src/os/linux/vm/os_linux.cpp:4014), pid=17525, tid=17525 # assert(thread != __null) failed: Missing current thread in SR_handler #

That one was never attached to the jvm and hence signal handling does not work there (for a start, Thread::current() never got set).
