title: Support for package "com.ibm.misc" and its classes
body: <p>I wanted to decode a Base64 string in my XPage for which I was using <code>sun.misc.BASE64Decoder</code> class. But according to Java <a href="http://www.oracle.com/technetwork/java/faq-sun-packages-142232.html" rel="nofollow">developer should not write programs that call 'sun' packages</a>. I was searching for an alternative when I stumbled on <code>com.ibm.misc.BASE64Decoder</code>. It worked for me with same results as <code>sun.misc.BASE64Decoder</code>. So I would like to know if it is okay for developers to use this package and its classes? Or is it to be avoided like 'sun' package?</p>
  
  <p>Also I know that I can use <a href="http://commons.apache.org/codec/" rel="nofollow">Apache Commons</a> for Base64 but I would like to minimize my dependency on external JARs.</p>
