------------------------------------------
set to 2.5 beta 1
> generic bounds ignored by type checking
> ---------------------------------------
>
> Key: GROOVY-6659
> URL: https://issues.apache.org/jira/browse/GROOVY-6659
> Project: Groovy
> Issue Type: Bug
> Components: Static compilation, Static Type Checker
> Affects Versions: 2.3.0, 2.2.3, 2.4.0-beta-3
> Reporter: Jochen Theodorou
> Fix For: 2.5.0-beta-1
>
>
> {code:Java}
> class A{}
> class B{}
> @groovy.transform.CompileStatic
> class Helper<V extends A> {
> public Helper(Closure<V> cl) {}
> }
> @groovy.transform.CompileStatic
> static <C extends B> void extensionMethod(Closure<C> cl) {
> new Helper<C>(cl)
> }
> {code}
> The example is inspired by the fix done for GROOVY-6657, not sure versions
> before are affected, since this kind of code failed before. So it might be
> seen as regression.
> Anyway, the code above should not compile, since Helper cannot extend A and B
> at the same time.
