> Give an error message rather than logging the error and then crashing later because the JVM can't detect stack overflow. In a resource exhausted situation, thread creation is also failing. This is the vm_exit_out_of_memory message printed:
>
> `$ java -XX:+UseNewCode -version
> [0.003s][warning][os,thread] Attempt to protect stack guard pages failed (0x00007f606b249000-0x00007f606b24d000).
>
> There is insufficient memory for the Java Runtime Environment to continue.
> Native memory allocation (mprotect) failed to protect 16384 bytes for memory to guard stack pages
> An error report file with more information is saved as:
> /16mprotect/hs_err_pid30596.log`
