This method is broken: it may return false for the equal keys.
CollationKey.compareTo() method doesn't have this bug.

--------------Here is the method's source ------------------------
    public boolean equals(Object target) {
        if (this == target) return true;
        if (target == null || !getClass().equals(target.getClass())) {
            return false;
        }
        CollationKey other = (CollationKey)target;
        return key.equals(other.toString()); <--!!! The bug is here: toString()
                                                !!! method is not defined in
                                                !!! the CollationKey class.
    }


---------Here is the test demonstrating the bug (CKTest.java) --------------

import java.text.*;

public class CKTest {
  public static void main(String args[]) {
    RuleBasedCollator en_USCollator = (RuleBasedCollator)
        Collator.getInstance(java.util.Locale.US);
    CollationKey ck1=en_USCollator.getCollationKey("a String");
    CollationKey ck2=en_USCollator.getCollationKey("a String");

    System.out.println("compare: "+ck1.compareTo(ck2));
    System.out.println("equals: "+ck1.equals(ck2));
  }
}
---------Output from the test---------------------
% java CKTest
compare: 0
equals: false
