+%description
+Base64Coder is a fast and compact Base64 encoder/decoder class. There is no Base64 encoder/decoder
+in the standard Java SDK class library up to Java 7. The undocumented classes sun.misc.BASE64Encoder
+and sun.misc.BASE64Decoder should not be used (explanation). Since Java 8 there is now java.util.Base64.
