Description

The folowing Java code:

public class HelloWorld {
	private String[] names;
	public String[] getNames() { return names; }
	public void setNames(String... names) { this.names = names; }

	public String toString() {
		return "Hello " + join(getNames());
	}

	private String join(String[] strings) {
		StringBuilder sb = new StringBuilder();
		String delim = "";
		for(String string : strings) {
			sb.append(delim).append(string);
			delim = ", ";
		}
		return sb.toString();
	}

	public static void main(String[] args) {
		HelloWorld helloWorld = new HelloWorld();
		helloWorld.setNames("Morten", "Riccardo", "Anders");
		System.out.println(helloWorld.toString());
	}
}

produces the same output when compiled in Java or in Groovy 1.8.8 (the names joined with commas), but in Groovy 2.0.5 it produces: Hello [Ljava.lang.String;@4e5a67df

Found while trying to demonstrate how to simplify Java code in Groovy (not very cool...)
