* Closes#5863
The "dateLibrary" option for java, sadly, sets a mustache value "java8". This change updates this so that "java" in the mustache
libraries means what it should mean - use all java8 classes. In this case, there's no need for the third party Base64 library
as java8's JDK has this built in. In my view, the "dateLibrary" should be deprecated but that should be a separate PR.
