------------------------------------------------
Hi Bryan,
If the earlier errors were not the reason, is it something to do with this
warning:
[javadoc]
/home/hudson/hudson-slave/workspace/Derby-trunk/trunk/java/testing/org/apache/derbyTesting/functionTests/tests/lang/XplainStatisticsTest.java:621:
warning - @param argument "s:" is not a parameter name.
I have accidentally put a "colon" there after s.
The final log at the end says following:
javadoc:

I'm not quite sure what is this annotation refers to? You have any idea?

> I think it would be great to see some work in the area of tools for helping
> with the analysis of complex query execution. Quite frequently, users of
> Derby have trouble comprehending (a) how their query is being translated
> into a query plan by the optimizer, and (b) what the execution-time resource
> usage of the various parts of the query is.
> There are low-level features in Derby which capture this information and
> record it, such as logQueryPlan, and the XPLAIN tables, but there is a lot
> of opportunity for designing higher-level tools which can process the query
> plan and execution statistics information and present it in a more
> comprehensible fashion.
