This is because you expression is definitely not a valid cron expression. Check the documentation for details (very complex and lengthy). Cron has 7 fields: second, minute, hour, day of months, months, day of week, year. Only "year" is optional, thus any expression must either have 6 entries (w/o year) or 7 (with year).

Your expression has only 5 entries...

Try: 0 0 */12 * * ?
