> When the Derby Log Viewer is rendered on the Servers Log page, the DerbyLogHelper.java
copying ALL lines from derby.log and sending it back as a request attribute.  As the Derby
logfile grows, this will consume more server cycles and eventually impact other user apps
and response time.
> Also, the BufferedReader/FileReader is never closed, so this will leak a file handle
everytime the page is rendered.
> This portlet needs to be replaced with the logmanager/LogViewerPortet implementation,
so users can choose how many lines to display....
