C=C3=A9sar Izurieta updated GROOVY-7512:
-----------------------------------
    Description:=20
When running:

{code:title=3Dtest.groovy|borderStyle=3Dsolid}
class X {
    Closure action =3D {}
}

trait T {

    void say(String text) {
        println text
    }

    @groovy.transform.CompileStatic
    X getX() {
        new X(action: {
            say "Hello!"
        })
    }

}

class A implements T {
}

new A().x.action()
{code}

The following exception is thrown:

{code}
Caught: java.lang.ClassCastException: java.lang.Class cannot be cast to T
java.lang.ClassCastException: java.lang.Class cannot be cast to T
=09at T$Trait$Helper$_getX_closure1.doCall(Test2.groovy:14)
=09at T$Trait$Helper$_getX_closure1.doCall(Test2.groovy)
=09at Test2.run(Test2.groovy:23)
{code}

This is only happening on groovy 2.4.4. Removing the static compilation ann=
otation or reverting to groovy version 2.4.3 makes the code work.=20

The commit that is causing this problem seems to be: 1bbed25aa3a08bc0cb7e14=
