You are correct that the event handler just waits for keys, mouse clicks, and similar events. However, the event handler is entirely managed by the JRE, and thus is outside my control. I have implemented a partial fix for this by lowering the priority of the animation thread and the movement and laser processor thread to the minimum, so they don't needlessly waste CPU time when they have nothing to do. Bizarrely, this causes CPU usage to go down while the movement/laser thread is working but go back up to 100% when not doing anything.

Excluding worker threads the JRE makes for its own purposes, there are basically 3 threads that run constantly while the game is playing: The event handler thread (created and started automatically), the movement and laser processor thread (spins in a loop; yields to other threads if it has no work to do; when there IS work to do, handles movement of the tank and shooting lasers - both by you and anti-tanks), and the animator thread (constantly animates all the game objects - if turned off in the preferences, this thread never starts; sleeps periodically to delay the animation enough to make it realistic).
