                 URL: https://issues.apache.org/jira/browse/GROOVY-10116

          Components: Static Type Checker

I have the following Groovy program.

@groovy.transform.TypeChecked
class Test<T> {
  public void foo() {
    Foo<T, Long> x = new Foo<T, Long>(new Bar<T, Long>());
  }
}

class Foo<X, T> {
  public Foo(Bar<X, T> y) {}
}

class Bar<X, T> {}

{code}
h2. Actual Behavior

The program does not compile, and I get the following error.
{code:java}
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
Test.groovy: 4: [Static type checking] - Cannot call Foo#<init>(Bar<T, java.lang.Long>) with arguments [Bar<T, java.lang.Long>]
 @ line 4, column 22.
       Foo<T, Long> x = new Foo<T, Long>(new Bar<T, Long>());
                        ^

1 error
{code}

Compile successfully.
