[opencms-dev] Scheduled job, that I created programmatically, is causing problems (manual creation works fine though)

Hi Marthias,
In documentation, you see the method:
// site roots must never end with a "/"
Try put "/some/path", not "/some/path/". do not put the "/" at the end.
Good luck,
Deiverson
