I'm curious if there was a conclusion on this one. I assume SCTP_WERROR
was originally intended for building libsctp (not libnio) so it would be
strange to add to SCTP_WERROR to disable -Werror for issues coming from
the file system code. One other thing that isn't clear is why there
aren't other warnings as there are many other JNI functions in this
source file that don't use the "jclass this" parameter.
