Subject Re: [jira] Commented: (DERBY-1471) Implement layer B streaming for new methods defined in JDBC4.0
Date Sat, 11 Nov 2006 12:21:29 GMT

Reading the code ( BaseMonitor.java, modules.properties, 
InternalDriver.java and so on ), 
it seems that possible class of engine is different between running 
environment ...

Then, I think it is needed to consider when the class is not expected class.

Best regards.
