[sctp-dev] Use SCTP with Java 1.6?

[Dennis Hjort]

Hi Christopher ! 

I've been reading your posts regarding this topic, and downloaded the
source, and applied the patch. Now I would like to compile a jdk6
compatible sctp-lib! :-) 

As you already know, our management is holding of moving up to JDK7
until a standard release, maybe even longer, and we are now trying to
cut of performance costs in the product we are building, and now we even
have numbers on what our implementation using the JNI library +
additions to our eventkernel to handle the blocking channels is costing
in performance, so it would be great to be able to use the sctplib with
JDK6 already ! :-)

So, if it's possible I would appreciate the detailed instructions on how
to get it working with JDK6 ! :-)

With kind regards

// Dennis

Hi Michal,

I was trying to come up with a list of things to do to get the SCTP
implementation working on JDK6, when I came across a previous attempt I
made at it. To my surprise I had actually got further than I thought,
and I found a list of changes I wanted to push into JDK7 so make this
simpler ( as well as a few new ones ).

 From that I created;
  6915313: (sctp) Reorganize implementation to make it more feasible to
port to JDK6

Webrev:
   http://cr.openjdk.java.net/~chegar/6915313/webrev.0/webrev/

With these changes applied we can simply take the JDK7 SCTP code, and
with two very minor edits have it run with JDK6. I did this and have it
running with JDK6u17. Without the above mentioned changes it is a little
more tricky because you need to make many more edits and recompile the
native code.

I will be requesting a review of 6915313 and hope to be in a position to
push it early next week. I can then send detailed instructions of how to
get it working with JDK 6.

-Chris.
