Description

When I click on Admin ? Instrumentation Log Reader I get an error.

This is a stock install of opennms 1.8.3 (via http://debian.opennms.org package archive) on Ubuntu 10.04.

I'll attach the relevant error from jetty.log.

This was caused by trying to inspect the modification time on a null log entry (probably when the instrumentation log is empty). I've added a check for this case that will prevent this problem. Marking as fixed.

Found a couple more NPE sources. Also, we should indicate to the user when we don't have any data and provide a hint on configuring logging so that we'll get some.
