To kill off the agents thread can't you just feed them a runnable that ends
when the model ends?
To kill off the display associated with them, tell the agents thread, right
before it ends, to release a permit to an external  (and initially
empty) semaphore.
Tell the thread calling dispose() on the jframe to acquire X (number of
agents) permits from the semaphore before  killing the jframe and it should
coordinate by itself.

Understand however that concurrency is easy to screw up and you might want
to bone up on it rather than trusting my foggy memories of it.
