>             Project: Groovy
>          Issue Type: Bug
>          Components: Static compilation
>    Affects Versions: 2.3.4
>            Reporter: Mauro Molinari
>            Assignee: Daniel Sun
>            Priority: Major
>             Fix For: 2.6.0-alpha-4, 3.0.0-alpha-3, 2.5.0-rc-3

>
> Consider the following Java class:
> {code:java}
> package l;
> public class LJava <T extends Number> {
>    public T doSomething() {
> 	   return null;
>    }
> }
> {code}
> and the following Groovy class:
> {code}
> package l
> import groovy.transform.CompileStatic;
> @CompileStatic
> class L extends LJava<Integer> {
> 	Integer doSomething() {
> 		super.doSomething()
> 	}
> }
> {code}
> Static compilation fails because Groovy thinks that {{doSomething()}} for {{LJava<Integer>}} returns {{Number}} instead of {{Integer}}.
