* user of this class, could be used on JDK 1.1 compatible JVM-s and the others.
* In the first case, no security mechanism is provided in the JVM, so there is
* no need to execute doPrivileged blocks at all. In the second case the real
* java.security.AccessController, java.security.PrivilegedAction and
* java.security.PrivilegedExceptionAction are used to execute doPrivileged
* blocks.
*
* @deprecated java.security package API should be used in order to execute
* appropriately doPrivileged blocks. The provided implementation is
* fake and is left only for backward compatibility.
