The Checker Framework enhances Java’s type system to make it more powerful and useful. This lets software developers detect and prevent errors in their Java programs. The Checker Framework includes compiler plug-ins ("checkers") that find bugs or verify their absence. It also permits you to write your own compiler plug-ins.

There is a newer version: 3.42.0

/**
 * A meta-annotation indicating that an annotation type prevents whole-program
 * inference. For example, if the definition of @Inject is
 * meta-annotated with @IgnoreInWholeProgramInference:

 *   @IgnoreInWholeProgramInference

 *   @interface Inject { }

 * then no type qualifier will be inferred for any field annotated by
 * @Inject.
 *
 * 
 * This is appropriate for fields that are set reflectively, so there are
 * no calls in client code that type inference can learn from.
 * Examples of qualifiers that should be meta-annotated with
 * @IgnoreInWholeProgramInference include
 * @Inject,
 * @Singleton,
 * and
 * @Option.
 *
 * 
 * See {@link org.checkerframework.common.wholeprograminference.WholeProgramInferenceScenes#updateInferredFieldType}
