>             Project: Groovy
>          Issue Type: Bug
>          Components: Static compilation, Static Type Checker
>    Affects Versions: 4.0.0-alpha-3

> I have the following Groovy program.
> {code:groovy}
> class A<T> {}
> class B {}
> @groovy.transform.TypeChecked
> class C<G extends B[]> extends A<G> {} // It works if G extends B
> {code}
> h2. Actual Behavior
> The program does not compile, and I get the following error.
> {code:java}
> org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
> Main.groovy: 8: unable to resolve class G
>  @ line 8, column 34.
>    class C<G extends B[]> extends A<G> {}
>                                     ^
> 1 error
> {code}
> h2. Expected Behavior
> I would expect the compiler to report a message like the one that javac reports:
> {code:java}
> error: unexpected type
> class C<G extends B[]> extends A<G> {}
>                    ^
>   required: class
>   found:    B[]
> 1 error
> {code}
> h2. Comment
> Note that with 3.0.8, the compiler does not report any error.
> h2. Affected Version
> This programs have been tested with the compiler from the master (commit: 8ea882a587ce3183c95ea1bc19dfc44367dc292e), and 4.0.0-alpha-3.
