Description
If a string which does not follow the rtf documentation (http://www.ietf.org/rfc/rfc2045.txt -> 6.8) is given as an argument for the decoding methods of the class org.apache.axiom.om.util.Base64, an exception for InvalidArgument should be thrown, but it isn't.
For example an invalid string for decoding would be the string "me". So if we call the method this way:
Base64.decode("me");
the behaviour we expect is an exception to be thrown.
