enabled by default, meaning that API fields no longer allow IP or CIDR
  values with extraneous leading "0"s (e.g., `010.000.000.005` rather than

            byte[] invalidType = new byte[100];
            System.arraycopy(Type2Message.NTLMSSP_SIGNATURE, 0, invalidType, 0, Type2Message.NTLMSSP_SIGNATURE.length);
            // Set message type to something other than NTLMSSP_TYPE2
            Type2Message.writeULong(invalidType, 8, Type2Message.NTLMSSP_TYPE1);

    timing out, and that was a lousy policy. If establishing a connection,
    reading the next byte from a connection, or writing the next byte to a
    connection takes more than 10 seconds to complete, you’ll need to adjust
    the timeouts manually.
