        Specified by:
        registerJavaMethod in interface MethodRegistry
        Parameters:
        alias - the alias of the method. This is the name how the BASIC program will refer to the method. Although the BASIC source code makes it optional to provide an alias it is not optional here. It may be same as the string contained in the parameter methodName but it should be passed here and should not be null
        klass - the class in which the method is implemented.
        methodName - the Java name of the method.
        argumentTypes - the argument classes that form the signature of the method together with the name and class of the method.
        Throws:
        BasicRuntimeException - is thrown if the registration of the alias is not unique in the actual interpreter. You can not register a name for a method and then later the same alias for a different method.
