We are currently seeing random networking tests failing on Windows with "An operation was attempted on something that is not a socket", another example is JDK-8198871. The issues seem to have started in jdk-11+1 when classic networking was changed from using finalizers to the new Cleaner API. The TwoStack* implementation of java.net.DatagramSocketImpl seems to have code paths that close sockets that are registered with the cleaner. When the Cleaner runs, it closes the sockets used by some victim test that is running later in the same VM.
