Rob Godfrey commented on PROTON-154:
------------------------------------
I've applied the patch for proton-j as a temporary measure since this is
causing Hiram issues right now... but this is not a real solution - it will
just manifest in different use cases being broken.
> link attach, detach, attach sequence on single session does not result in a
> new link for the 2nd attach
