Good work was done in JDK-8066776 to remove the runtime dependency on sun.misc.BASE64Decoder and BASE64Encoder, but there is still a static dependency on these types in jdk.deploy/share/classes/com/sun/deploy/util/Base64Wrapper.java. This will be a problem when these types are removed in JDK-8144479.

The solution is to access the coders reflectively.
