[jira] Created: (HARMONY-1102) [classlib][luni] Method readResolve() missing in java.util.Collections.EmptySet, EmptyList and EmptyMap.

[classlib][luni] Method readResolve() missing in java.util.Collections.EmptySet, EmptyList and EmptyMap.
--------------------------------------------------------------------------------------------------------

                 Key: HARMONY-1102
                 URL: http://issues.apache.org/jira/browse/HARMONY-1102
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
            Reporter: spark shen


Method readResolve() missing in java.util.Collections.EmptySet,
EmptyList and EmptyMap.The instances of "public static final Map
EMPTY_MAP","public static final Set EMPTY_Set" and "public static final List
EMPTY_List" should be a singleton respectively according to the following test
cases, and should keep as a singleton respectively  after de-serialization.

JIRA testcase:
   public void test_EmptyList_Singleton() throws Exception {
        List theEmptyList = Collections.EMPTY_LIST;
        List same1 = (List) SerializationTester
                .getDeserilizedObject(theEmptyList);
        List same2 = (List) SerializationTester
                .getDeserilizedObject(theEmptyList);
        assertSame(same1, same2);
        assertSame(same1, theEmptyList);
    }

    public void test_EmptyMap_Singleton() throws Exception {
        Map theEmptyMap = Collections.EMPTY_MAP;
        Map sameMap1 = (Map) SerializationTester
                .getDeserilizedObject(theEmptyMap);
        Map sameMap2 = (Map) SerializationTester
                .getDeserilizedObject(theEmptyMap);
        assertSame(sameMap1, sameMap2);
        assertSame(sameMap1, theEmptyMap);
    }

    public void test_EmptySet_Singleton() throws Exception {
        Set theEmptySet = Collections.EMPTY_SET;
        Set sameSet1 = (Set) SerializationTester
                .getDeserilizedObject(theEmptySet);
        Set sameSet2 = (Set) SerializationTester
                .getDeserilizedObject(theEmptySet);
        assertSame(sameSet1, sameSet2);
        assertSame(sameSet1, theEmptySet);
    }
JIRA test result
     RI 5.0 passes this test, but Harmony fails.

I will attach a patch to fix this problem.

Best regards
Spark shen

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

Spark, IIRC on the mailing list,  we have agreed to use new serialization framework proposed by Stepan[1], and at the same time stop using the old SerializationTester, so I suggest you to update your patch about the test. Any problem, please let me know, thank you.
