Should this log message be moved up into the finally block so it's called
if an Exception is thrown?

> Assignee: Kevin Chilton
> Priority: Major
>
> We need an application that watches the QueryChangeLog to see when the
> isActive state of queries changes and then reacts to the state change. If
> isActive goes to true, the system must start processing the query. If it is
> false, then it must stop processing the query. This application needs to
> start when the host machine starts. We plan to support CentOS 7.
