> Probably this is a regression, because groovyc 4.0.10 catches the error.
> Program:
> {code}
> import java.util.*;
> public class Test {
>     public static <T extends Number> void test() {
>       List<T> d = null;
>       d.add(false);
>     }
> }
> {code}
> h3. Actual behavior
> Groovyc compiles the  code
> h3. Expected behavior
> Groovyc rejects the code with a message of the form:
> {code}
> org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
> test.groovy: 8: [Static type checking] - Cannot find matching method java.util.List#add(boolean). Please check if the declared type is correct and if the method exists.
>  @ line 8, column 7.
>          d.add(false);
>          ^
> 1 error
> {code}
> Tested against master
