Subject [jira] Commented: (DERBY-273) The derbynet/dataSourcePermissions_net.java test fails intermittently
Date Sun, 22 May 2005 21:08:51 GMT
     [ http://issues.apache.org/jira/browse/DERBY-273?page=comments#action_65999 ]
     
Kathey Marsden commented on DERBY-273:
--------------------------------------

When network server closes a session, it tries to perform a rollback on the connection before
closing the connection. If it encounters an exception during rollback it treats the exception
as an unexpected exception and prints the error to the console. 

However, in this case, the database has been intentionally shut down and the error on rollback
is expected. Network Server should treat an error on rollback, when closing a session, as
an expected exception if the database has been intentionally shut down. 

The intermittent nature of this diff seems to be related to when the session for the disconnected
client that shutdown the database gets cleaned up. 

When the test fails, this is the trace in the tmp file:
