> When I did some profiling of Derby running with the test client in
> DERBY-1961, the profiling tool (Sun Studio's collect and analyzer) reported
> that BasePage.getPageId() used much CPU (although the method does almost
> nothing). Adding the 'final' keyword to the method definition seems to reduce
> the CPU usage and increase the throughput.
