[classlib][luni] java.util.Hashtable.remove(.) throws StackOverflowError while RI doesn't
-----------------------------------------------------------------------------------------

                 Key: HARMONY-6203
                 URL: https://issues.apache.org/jira/browse/HARMONY-6203
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
    Affects Versions: 5.0M9
            Reporter: Kevin Zhou
             Fix For: 5.0M10


Given a test case below [1], RI passes it while HARMONY throws a java.lang.StackOverflowError error. The stack trace is given as [2], this error is thrown due to its hashCode method.

[1] Test Case:
public void test_HashTable_remove() {
    Hashtable hashTable = new Hashtable();
    Set keySet = hashTable.keySet();
    hashTable.put(hashTable, keySet);
    hashTable.remove(hashTable);
}

[2] Stack Trace:
java.lang.StackOverflowError
