Description

    private void someMethod(){}
    private void falsePositive(){
        try{
            someMethod();
        }
        catch(RuntimeException e){
            if (e instanceof NullPointerException){
                throw e;
            }
            //false positive for possible null pointer
            Throwable cause = e.getCause();
        }
    }

Is it even possible for e to be null?
