Hi Ken,

That commit (rev 1547534) uses JDK 7 specific features (specifically java.net.StandardSocketOptions)
so the build is now breaking.  Please see

https://builds.apache.org/view/M-R/view/Qpid/job/Qpid-proton-j/495/console

Can we enable tcp no delay on the socket instead?

regards, Keith.

btw.  to which components does this Jira apply? The Jira title starts [proton-c]..., but the
assigned component is proton-j.

> The method used to distribute credit to receiving links may lead to starvation when the
number of receiving links is > the available credit.
> The distribution algorithm always starts with the same link - see messenger.c::pn_messenger_flow()
