Okay, so I think the issue is that EPROTONOSUPPORT is not handled as I would have expected that to cause UOE to be thrown. I suspect the isSCTPSupported check in Util.java (used by the tests in jdk/test/com/sun/nio/sctp) are masking this. My memory is that there were several relilability issues with SCTP in the early days and it might be that this is why they skip when any error is returned creating the SCTP socket.
