Not JDK, but you can run Tomcat with a security manager to prevent
such calls.  You've not told us which version of Tomcat you're
running, so I'll link the most recent (Tomcat 6.0.x) document:
http://tomcat.apache.org/tomcat-6.0-doc/security-manager-howto.html

Tuning the security manager often takes quite a lot of work, as you
need to find out what to allow as well as what to deny.
