What can I do with Java 1.4?
I made one (Before realizing it'd already been done) to backport newer language features to Java 8 and it was pretty easy to bundle it up as a maven plugin. But going back all the way to 4 will be a notable increase in difficulty. Retrolambda goes to 1.5 but not all the way to 4. You could hypothetically add a layer on top of it to support 1.5 -> 1.4. That or roll a fork of it.
What are some alternatives?
Javaslang - vʌvr (formerly called Javaslang) is a non-commercial, non-profit object-functional library that runs with Java 8+. It aims to reduce the lines of code and increase code quality.
jOOλ - jOOλ - The Missing Parts in Java 8 jOOλ improves the JDK libraries in areas where the Expert Group's focus was elsewhere. It adds tuple support, function support, and a lot of additional functionality around sequential Streams. The JDK 8's main efforts (default methods, lambdas, and the Stream API) were focused around maintaining backwards compatibility and implementing a functional API for parallelism.
