Use the JSR 305 Annotations to specify what can and what can’t be null

[ExE-Boss]

The JSR 305 Annotations library provides multiple annotations in the javax.annotation package, including @Nullable and @Nonnull which specify what can and can’t be null respectively.

The library also provides other annotations, such as @Immutable to specify immutable objects.
It’s also used by Minecraft Forge.

dependencies {
	compile group: "com.google.code.findbugs", name: "jsr305", version: "1.3.9"
}
