Subject Re: Are connectEventListeners supported with 10.3? [DERBY-3172]
Date Fri, 02 Nov 2007 01:32:31 GMT
FYI - opened JIRA issue *DERBY-3172 
<https://issues.apache.org/jira/browse/DERBY-3172> - 
connectionEventListeners* are in the test harness so I assume they are 
supported and should be working.  Problem also appears to happen when 
using the EmbeddedDatasource
