The error code -70015 corresponds to APR_NOTFOUND. I've also tracked it down into the APR code, and it looks like the problem comes from the kevent syscall returning ENOENT when MINA is doing the Poll.remove() call.
I should note that the same code functions "normally" on Linux using the APR Transport, so I'm not sure if the problem is MINA's use of APR or APR's use of kqueue/kevent on FreeBSD.
