This happened in jdk9 nightly 02-22 and 02-21, when running UDP tests on Win 8 64 bit.
There is no such issue with JDK 9 b02 promotion build.

I can reproduce with following snippet of code:
       try (DatagramSocket ds = new DatagramSocket();){
            
            ds.getLocalAddress();
        } catch (SocketException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

When invoking getLocalAddress(), the vm is immediately crushed.
