loop to deliberately cause program to crash?

[Pouncer]

class GamePlayer {
    int doSomeMove() {
	// for loop put in here deliberately to cause timeout
	for (;;) {
	}

	return 5;
    }
}

i'm trying to test my system with timeouts and stuff, by doing malicious coding on purpose. but the above doesn't work anyway as it says
Test.java:40: unreachable statement
return 5;
^
1 error

how could i make this work to test stuff?

Make a boolean that's true then have a while loop with the boolean as its parameter.

Let it be a class member, and make sure it's neither const nor final
