Edward opened SPR-12871 and commented

The constructor for the org.springframework.scheduling.support.CronSequenceGenerator will go into an infinite loop if one of the fields is of the form n/0

For example

public static void main (String[] s) {
    new CronSequenceGenerator("*/0 * * * * *");
    System.out.println("We will never get here");
}

I guess that either the /0 should be ignored, or it should throw an IllegalArgumentException

Affects: 3.2.13, 4.1.6
