beepcore implementation

Hi,

Does beepcore-j limit the size on messages (in particular ANS & RPY).  I
recently began using beepcore-j, and initially my messages were roughly
500 bytes and everything worked very well.  The message size has now grown
to about 5k, and after a few messages, the processing stops, as if
receiveANS and receiveRPY are no longer being called.  I tried spawning a
new thread to handle read the message input stream, and it didn't seem to
help very much.  Do I need to break the messages up into smaller pieces,
or am I doing something else incorrectly?

Thanks for any help!
