Introduction

This small document will explain how I cracked version 3.3.1 of JNIC. (https://jnic.dev)

Motive

The motive of this crack was simply to test the strength of "DRM" applied to JNIC.

Methodology

Discovering the funny

Upon opening the JNIC JAR in a decompiler, I quickly discovered a 'JNICLoader' class, which contained methods whos first parameter were MethodHandles (all of these methods were named 'invoke').

The Rules of React

All libraries have subtle rules that you have to follow for them to work well. Often these are implied and undocumented rules that you have to learn as you go. This is an attempt to document the rules of React renders. Ideally a type system could enforce it.

What Functions Are "Pure"?

A number of methods in React are assumed to be "pure".

On classes that's the constructor, getDerivedStateFromProps, shouldComponentUpdate and render.
