IBM WebSphere Server JVM properties

Question

There are certain JVM properties (such as timezone) which can be changed by application deployed on WebSphere server. Such changes affects all the application on that server. Is there a way by which we can prevent applications from changing JVM properties at runtime. I am wondering if we can set some property in WebSphere server which will then prevents applications changing anything on JVM at runtime. Its like having JVM properties controlled by IBM WebSphere server rather than applications deployed on it.
