> I have the following Groovy program.
> {code:groovy}
> @groovy.transform.TypeChecked
> class Bar<L, T extends L> {
>     T x;
>     public Bar(T x) {
>       this.x = x;
>     }
> }
> {code}
> h2. Actual Behavior
> The program does not compile, and I get the following error.
> {code:java}
> org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
> Bar.groovy: 5: [Static type checking] - Cannot assign value of type L to variable of type T
>  @ line 5, column 16.
>          this.x = x;
>                   ^
> 1 error
> {code}
> h2. Expected Behavior
> Compile successfully.
> h2. Comment
> This bug is probably a regression because it compiles successfully with 3.0.8 and 4.0.0-alpha-3.
> h2. Affected Version
> This programs have been tested with the compiler from the master (commit: c36c8bf3d24ce41e972e3f3e7a5763acf96f46b1).
