Propietary api class

[Joseph Smithern]

In my Tomcat 6.0.20 container I am using sun.misc.BASE64Encoder to get NTLM Intranet username and everything works. Unfortunately I get the below warning message after I compile the class.

Auth.java:3: warning: sun.misc.BASE64Encoder is Sun proprietary API and
 may be removed in a future release import sun.misc.BASE64Encoder;
               ^
1 warning

It seems the sun.misc.BASE64Encoder is Sun proprietary API and is available from the rt.jar? I was wondering if I should put the rt.jar in my web app lib folder (\WEB-INF\lib) just in case it is removed from the jvm in the future?

I would not. As has been evidenced in many posts reporting arcane errors, mucking around with the class loading of Java and container classes is like painting a big red target on your chest.

I'd either find an alternate API, or worry about it when it actually becomes a problem.
