JRE in Crystal Reports Viewer?

I was looking at the components that are installed with Crystal Reports Viewer and noticed that there is an instance of Java in the program directory "C:\Program Files\Business Objects\Crystal Reports Viewer XI\jre\bin" . The JRE version installed within the application's program is not the latest update for the particular Java version, 1.6.0. Does anyone know how can I patch the viewer so that it is up to date with the latest Java update? My concern is the older versions of the JRE have security vulnerabilities. Is there an upgrade to the software that contains the latest JRE update for the Java version installed with Crystal Reports viewer? Right now for JRE 6.0 the update is version 15. Any help is appreciated.
