When a Java application uses the Java Native Interface (JNI) to
					call code written in another programming language, it can expose the application
					to weaknesses in that code, even if those weaknesses cannot occur in
					Java.Many safety features that programmers may take for granted simply do not
						apply for native code, so you must carefully review all such code for
						potential problems. The languages used to implement native code may be more
						susceptible to buffer overflows and other attacks. Native code is
						unprotected by the security features enforced by the runtime environment,
						such as strong typing and array bounds checking.
