Subject [jira] [Updated] (DERBY-6628) Intermittent error in TriggerGeneralTest
Date Thu, 28 Aug 2014 22:45:08 GMT

     [ https://issues.apache.org/jira/browse/DERBY-6628?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Dag H. Wanvik updated DERBY-6628:
---------------------------------

    Attachment: derby-6628-2.diff

Talked to Knut about this patch a bit, we decided to retry the assert for the lock result
set for a while so rule out slow, lingering (re)compilation locks. If the locks of the system
tables hang around for a minute (max waiting time), something fishy is going on and it would
seem the locks are belong to the user transaction, whereas we would have expected (re)compilations
to happen in a sub transaction.

Uploading [^derby-6628-2.diff]. We'll run with this for a while, and if we don't see this
issue again, close the issue.
