Scenario doesn't validate PULSE DURATION, throws ArithmeticException for illegal values

com.sun.scenario.Settings.set("com.sun.scenario.animation.pulse", "1001");

results in:

java.lang.ArithmeticException: / by zero
        at com.sun.scenario.animation.AbstractMasterTimer$MainLoop.updateNextPulseTime(AbstractMasterTimer.java:288)
        at com.sun.scenario.animation.AbstractMasterTimer$MainLoop.getDelay(AbstractMasterTimer.java:253)
...

Any value higher than 1000 causes this exception, probably because the runtime uses milissecond precision for PULSE_DURATION and any value > 1000 results is rounded to 0 somewhere.

Negative values (like -1) cause no harm, just like 0 they mean "default duration from monitor's frequency".
