 Description  « Hide
Run the attached selenium script. It creates a Content Source, and uses the sync schedule of

0/30 * * * * ?

which according to these docs
https://docs.jbosson.redhat.com/confluence/display/JON2/Applying+JBoss+Patches
http://www.opensymphony.com/quartz/wikidocs/CronTriggers%20Tutorial.html

Should mean "every 30 seconds". But this causes the creation of the content source to fail (see stack trace below). Even if this schedule is invalid it needs to fail more gracefully.

Selenium script to reproduce problem.

Further investigation shows that this is not 100% reproducible. The sync schedule (nor the value of any of the page inputs) is not enough to cause the failure. There's some random element to it.

I say try the script a few times (you may need to change the name of the content source each time you run it, or delete the old one). That should be enough to reproduce.

Perhaps the stack trace alone is enough to figure out what's wrong here.

jeff, what happens if you scale back the frequency of these sync schedules. i'm guessing that if the content source (or some related entity) is still being mucked with in one transaction, while another transaction attempts to start and use the same object. what happens if you scale this back to five minutes? it may just be the case that we have to serialize the sync requests, so that only one of them is running for some content source at the same time. i.e., launch a sync job (according to the schedule), but if job is already running, ignore this job request.

I can't reproduce this on qa build 6163. might have been fixed by rhq-655 .. but i'm just speculating.
