Class SecurityUtil

public final class SecurityUtil extends Object

This utility class associates a Subject to the current AccessControlContext. When a SecurityManager is used, * the container will always associate the called thread with an AccessControlContext * containing only the principal of the requested Servlet/Filter. This class uses reflection to invoke the invoke methods.
