JVM Security Wish List

I wish when you installed the Java JVM on a server you could have fine grained control to include only the components you are actually going to use and a security wizard to set up the default security policies, for instance. This would allow not installing additional unneccessary code and potential exploits. I try to remove each jar or directory I know I do not need but I do not know what every single file in the jdk is and whether I can safely remove it or not.
