[Groovy] Class BooleanMethodReturnsNullRule

class BooleanMethodReturnsNullRule
extends AbstractAstVisitorRule

Method with Boolean return type returns explicit null. A method that returns either Boolean.TRUE, Boolean.FALSE or null is an accident waiting to happen. This method can be invoked as though it returned a value of type boolean, and the compiler will insert automatic unboxing of the Boolean value. If a null value is returned, this will result in a NullPointerException.
