AsynchronousDatagramChannel implementation

[David Dabbs]

Hello.

Bug 6993126, http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6993126,
indicated that 

>We need to remove AsynchronousDatagramChannel before jdk7 goes into
lock-down mode. 
>This class was included for consistency reasons but was never required for
scalability 
>or other reasons. The implementation needs work and the JCK test coverage
is weak too. 
>We've agreed that the best thing is to remove it for jdk7 and look at it
again in jdk8.


ADC stayed in JDK7, but are the improvements in the jdk8 plan? What was
was/is deficient 
about the implementation? Perhaps it is something that could be contributed.


Many thanks,

David
