Spring - problem with task scheduler

I have a strange problem with task scheduler. Here are three tested configurations of pingProducer in my appliacationContext.xml. The first and the second work. The third, which should produce the ping every hour, doesn't - it produces the ping every minute. Am I missing something?

<!-- Ping scheduler - WORKS - every second -->
<task:scheduled-tasks>
    <task:scheduled ref="pingProducer" method="producePingRequest" cron="* * * * * ?" />
</task:scheduled-tasks>

<!-- Ping scheduler - WORKS - every minute -->
<task:scheduled-tasks>
    <task:scheduled ref="pingProducer" method="producePingRequest" cron="0 * * * * ?" />
</task:scheduled-tasks>

<!-- Ping scheduler - DOES NOT WORK - every minute -->
<task:scheduled-tasks>
    <task:scheduled ref="pingProducer" method="producePingRequest" cron="0 0 * * * ?" />
</task:scheduled-tasks>

<task:scheduled-tasks>
<task:scheduled ref="pingProducer" method="producePingRequest" cron="0 0 0/1 * * ?" />
</task:scheduled-tasks>

cron="0 0 0/1 * * ?" works because 0/x means run after every x hour from 0 o'clock.

Change to:

<task:scheduled-tasks>
    <task:scheduled ref="pingProducer" method="producePingRequest" cron="50 0 * * * ?" />
</task:scheduled-tasks>

EDIT: once per hour, on the 50th second
