There is no check for ENOPROTO in the JDK SCTP code. There is an implicit assumption that SCTP is "supported" when the native libsctp.so.1 library successfully loads and can be introspected. Maybe there should be an explicit ENOPROTO in Java_sun_nio_ch_sctp_SctpNet_socket0.
Maybe the machine in question has the libsctp.so.1 library, but the kernel module is not loaded or something?
