I am afraid not.
*/5 means on every hours that is a multiple of 5, not every five
hours. So it will run every day at hour 0, 5, 10, 15 and 20. Between
hour 20 one day and hour 0 the next day there is only 4 hours, not
the "every 5 hours" requested.
Just to confirm that I launched a cron job yesterday:
23 */5 * * * /home/java/on/crontest
It ran at 15:23, 20:23 and today at 0:23 and 5:23 and so on:
