The following script causes StackOverflowError:

Map map = new HashMap();
map.put(new MyKey("1"), "1");
map.get(new MyKey("1"));

public class MyKey
{
    private String m_key;

    public MyKey (String key)
    {
        m_key = key;
    }

    public String getKey ()
    {
       return m_key;
    }

    public int hashCode ()
    {
        return m_key.hashCode();
    }

    public boolean equals (Object o)
    {
        if (this == o) return true;
        if (!(o instanceof MyKey)) return false;
        MyKey key = (MyKey) o;
        return key.getKey().equals(m_key);
    }
}
