[ http://issues.apache.org/jira/browse/DERBY-997?page=all ] Andrew McIntyre reopened DERBY-997: -----------------------------------
> ClassCastException when executing queries with aggregates in app servers > ------------------------------------------------------------------------ > > Key: DERBY-997 > URL: http://issues.apache.org/jira/browse/DERBY-997 > Project: Derby > Type: Bug > Components: SQL > Reporter: Daniel John Debrunner > Assignee: Daniel John Debrunner > Fix For: 10.2.0.0, 10.1.2.3, 10.1.3.0 > > Classes that implement the aggregates such as MAX/MIN are loaded as > user-defined classes due to old support for user-defined aggregates. > If the class loader setup running Derby is not well set up these classes are > loaded in a different class loader space to Derby's class leading to > non-comparable classes due to the the same class (dependend or subper-class, > not sure which) being loaded twice. > While this may be a user setup bug, it has occured frequently leading to > wasted time resolving the issue, it would be better if Derby ensured its > classes were loaded consistently. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
