Description

For this Groovy class:

class TaggedsMap extends TreeMap {

    TaggedsMap() { super() }

    TaggedsMap(Comparator comparator) { super(comparator)}

    TaggedsMap(Map m) {
        super()
        putAll( m)
    }

    TaggedsMap(SortedMap m) {
        super()
        putAll (m)
    }
}

The following stub is generated:

public class TaggedsMap
  extends java.util.TreeMap  implements
    groovy.lang.GroovyObject {
public TaggedsMap
() {
super ((java.util.SortedMap<K, java.lang.Object extends V>)null);
}
public TaggedsMap
(java.util.Comparator comparator) {
super ((java.util.SortedMap<K, java.lang.Object extends V>)null);
}
public TaggedsMap
(java.util.Map m) {
super ((java.util.SortedMap<K, java.lang.Object extends V>)null);
}
public TaggedsMap
(java.util.SortedMap m) {
super ((java.util.SortedMap<K, java.lang.Object extends V>)null);
}
}

which isn't a valid Java code.
