Tomcat doesn't use anything like that much memory on its own. I suspect it is the application although the difference between Tomcat 6 and Tomcat 7 is unexpected. The only way to find out what is going on is to look at what is using that memory. You'll need to take a heap dump and/or use a profiler to find out.
