This is a java-agent that patches some of eclipse's classes so AST Nodes are handed off to Lombok
for modification before Eclipse actually uses them to compile, render errors, show code outlines,
create auto-completion dialogs, and anything else eclipse does with java code. See the *Transformer
classes in this package for more information about which classes are transformed and how they are
transformed.
