Tomcat does not release references to the servlet.  In fact, it's totally
up to the container (not to you) to decide how long a servlet instance
will stay initialized.

What you want to do is make sure that your *servlet* does not maintain any
references to the report results for the previously generated report.
Then, those objects can get GC'd.

Of course, you're still going to have problems when multiple users ask for
reports to be generated at the same time, if you've only got enough memory
to do one -- but that's a separate issue.
