[sctp-dev] Platform support for SCTP ?

[Christopher Hegarty - Sun Microsystems Ireland]

Hi Dennis,

I made changes to the API to remove some unnecessary dependencies on 
parts of the new JSR 203 socket completion work. I need to refactor 
these changes in the prototype.

Next, I will sync the sctp mecurial repository [1] ( for holding the 
prototype source ) with the OpenJDK tl repository [2]. Essentially, what 
we will have is the prototype implementation on top of the latest 
OpenJDK source.

There is a little infrastructure here that I am not familiar with, as 
well as completing the prototype refactoring, so it will be a take a 
some time to complete this. I hope to have this completed within the 
next two weeks. What we have then is a buildable repository that can be 
used to build the prototype.

I am working through an internal process here at Sun that will allow me 
to post binaries, built from said repository. This process may take a 
little longer to complete, but I am certainly pushing hard for it.

-Chris.
