Description

trait Test<V> {
    V value
}

class TestImpl implements Test<String> { }

Generates a stub like this

import java.lang.*;
import java.io.*;
import java.net.*;
import java.util.*;
import groovy.lang.*;
import groovy.util.*;

public class TestImpl
  extends java.lang.Object  implements
    Test<java.lang.String>,    groovy.lang.GroovyObject {
;
@groovy.transform.Generated() @groovy.transform.Internal() public  groovy.lang.MetaClass getMetaClass() { return (groovy.lang.MetaClass)null;}
@groovy.transform.Generated() @groovy.transform.Internal() public  void setMetaClass(groovy.lang.MetaClass mc) { }
@groovy.transform.Generated() @groovy.transform.Internal() public  java.lang.Object invokeMethod(java.lang.String method, java.lang.Object arguments) { return null;}
@groovy.transform.Generated() @groovy.transform.Internal() public  java.lang.Object getProperty(java.lang.String property) { return null;}
@groovy.transform.Generated() @groovy.transform.Internal() public  void setProperty(java.lang.String property, java.lang.Object value) { }
public  V getValue() { return null;}
public  void setValue(V value) { }
}

Note that value has type V instead of type String and the generic reference isn't declared in the class either.
