Dennis,

I've pushed the source changes for this and updated the libsctp.so on 
the instructions page [1]. Again, until the next JDK7 promotion you will 
need to get libsctp from there.

Alan made a good point during review of 6917317:

The SCTP implementation run with Sun's JDK6 is completely unsupported. 
The implementation uses Sun proprietary APIs that may be removed or 
changed in the future. Also, Sun's JDK6 is built with RHAS 2.1A and an 
old gcc. JDK7 is built with Fedora 9 and a more modern gcc. Everything 
should work (in theory) but there are bound to to be older Linux 
distributions where Sun's JDK6 works but libsctp will not work.
