Description

Follow up from GROOVY-6851 and GROOVY-9151. Consider the following:

@groovy.transform.CompileStatic
void greet(Object o = 'world', String s = o.toString()) {
    print "hello $s"
}
/*void greet() {
    Object o = 'world'
    greet(o, (String)o.toString()) // IncompatibleClassChangeError: Expected static method java.lang.Object.toString()Ljava/lang/String;
}*/
greet()

The STCV only looks at the default argument expressions, not the generated methods. So there still can be issues in the statically compiled result.
