method clear() in interface java.util.SortedSet throws java.lang.IllegalStateException

with b67 ,this exception is thrown on almost all platforms ( I tried on Solaris 8 & 9 , Win2000,win98 and Redhat7.1 )

with b66 the same works fine.


testcase
-------------------
 TreeSet treeSet = new TreeSet();
            for (int i = 1; i <=10; i++) {
                treeSet.add(new Integer(i));
             
            }
            SortedSet sortedSubSet =treeSet.subSet(new Integer(4),new Integer(10));
            sortedSubSet.clear();

Please see the attached testcase :
