This is most likely a Darwin/NIO2 bug but I wanted to let you know about it and
ask if you add an idea to work around this.

EDIT 1: It seems I can't comment on my own issue and so I can't answer to
Lyor Goldstein's suggestion. :(
We also tried with the Mina factory. Things are also very bad: the
"sshd-SshClient[68d28c46]-mina-thread-XXX" threads spin infinitely and lock the
cores they're running on. With mina 2.0.10, we don't get any log, but we do
with 2.0.13, where we get flooded with the following log:
"[info] 18:23:59.485 [WARN ] o.a.m.c.s.IoProcessor - Create a new selector.
Selected is 0, delta = 0"
With either factory, it seems sshd is broken on OSX. Even if it's not an issue
in production, it really is on development where OSX is our main platform.
Any help would be greatly appreciated, we'd rather not drop sshd for another
library. We can help debugging and testing, please advice.

> EDIT 1: It seems I can't comment on my own issue and so I can't answer to
> Lyor Goldstein's suggestion. :(
> We also tried with the Mina factory. Things are also very bad: the
> "sshd-SshClient[68d28c46]-mina-thread-XXX" threads spin infinitely and lock
> the cores they're running on. With mina 2.0.10, we don't get any log, but we
> do with 2.0.13, where we get flooded with the following log:
> "[info] 18:23:59.485 [WARN ] o.a.m.c.s.IoProcessor - Create a new selector.
> Selected is 0, delta = 0"
> With either factory, it seems sshd is broken on OSX. Even if it's not an
> issue in production, it really is on development where OSX is our main
> platform.
> Any help would be greatly appreciated, we'd rather not drop sshd for another
> library. We can help debugging and testing, please advice.

> EDIT 2: It seems we're hitting the same issue as described here:
