What version of Processing do you use? On the state of the PApplet code I have, line 2336 is in the middle of some comment!

This is not uncommon in Eclipse - make sure you click the red stop-box in Eclipse rather than close the sketch window.

or just stick explicit call to exit() method when your sketch contitions to stop. (eg. on certain key press).
