Implicit collections break if xml items are named after the implicit collection

Attached test case demonstrates. Here it is for easy browsing:

public static class Aquarium extends StandardObject {
private String name;
private LinkedList fish = new LinkedList();

public Aquarium(String name)

{ this.name = name; }

public void addFish(String fish)

{ this.fish.add(fish); }

}

public void testMatchingXmlElementAndJavaFieldName()

{ Aquarium aquarium = new Aquarium("hatchery"); aquarium.addFish("salmon"); aquarium.addFish("halibut"); aquarium.addFish("snapper"); String expected = "" + "<aquarium>\n" + " <name>hatchery</name>\n" + " <fish>salmon</fish>\n" + " <fish>halibut</fish>\n" + " <fish>snapper</fish>\n" + "</aquarium>"; xstream.alias("aquarium", Aquarium.class); xstream.addImplicitCollection(Aquarium.class, "fish", "fish", String.class); assertBothWays(aquarium, expected); }

Results in this error:
