Subject [jira] [Updated] (CAY-2574) FronBase integration issues
Date Thu, 02 May 2019 07:11:00 GMT

     [ https://issues.apache.org/jira/browse/CAY-2574?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Nikita Timofeev updated CAY-2574:
---------------------------------
    Description: 
Here are known problems with {{FronBase}} DB integration in Cayenne:
 * FronBase jdbc driver incorrectly returns {{null}} instead of statement (or throwing SQLException
at least) when {{connection.prepareStatement(sql, Statement.NO_GENERATED_KEYS)}} is called.
 We have simple workaround for this: just call {{connection.prepareStatement(sql)}}. But it
would be better if driver could do this for us, and there could be other places that do not
follow JDBC specification as we can't run all tests, see second issue.

 * Driver randomly hangs on socket read operation, see attached image for stack trace.
 This happens on every run of Cayenne tests (like just call {{mvn verify}} with FrontBase
connection)
