solve #240

hi, i'm starting a fork of this project because @shyiko seems to have gone away.
I'd like to merge and have this code, but I'd want it to both pass tests (not sure if they're passing), and have its own tests.

My fork is https://github.com/osheroff/mysql-binlog-connector-java if you want to open a PR there with continued work.

Sorry for the late responding, coming back to open source lately.
