IllegalMonitorStateException on wait() call
You need to be in a synchronized block in order for Object.wait() to work. Also, I recommend looking at the concurrency packages instead of the old school threading packages.

Why must wait() always be in synchronized block
What is the potential damage if it was possible to invoke wait() outside a synchronized block, retaining it’s semantics – suspending the caller thread?
