-------------------------------------------------------------------------

                 Key: HARMONY-1522
                 URL: http://issues.apache.org/jira/browse/HARMONY-1522

The method java.util.AbstractCollection.toString() throws NPE on Harmony and works OK on RI.

=================== test.java =========================
import java.util.concurrent.CopyOnWriteArraySet;

public class test {
    public static void main(String[] args) {
        System.out.println("cowas = " + new CopyOnWriteArraySet());
    }
}
===================================================
