@bestbeforetoday I've added recent changes for compatibility for Java 8, please review it.

[bestbeforetoday]

The build is failing since the code does not even compile.

Looking at the current set of changes (after the use of language features not available in Java 8 are reverted), the vast majority of the changes are reformatting of the code. A couple of variables are renamed and, in a couple of cases, the logic flow of the code is slightly reordered. What issue is this change addressing?
