### New properties in an existing class

When adding a property to an existing class (task, extension, domain object, etc), the API should consist of managed lazy properties.  However, some exceptions need to be made to keep backwards compatibility with existing builds.

This is preferred when the implementation type is internal:

```groovy

		expectedSync: false,
	},
	{ // 2. existing object replication config enabled, no versioning
		name:         "existing object replication config enabled, no versioning",
		info:         ObjectInfo{Size: 100},
		rcfg:         replicationConfig{Config: &configs[0]},
		expectedSync: false,
	},
	{ // 3. existing object replication config enabled, versioning suspended

                for (Plugin element : tgt) {
                    Object key = getPluginKey(element);
                    Plugin existing = master.get(key);
                    if (existing != null) {
                        mergePlugin(element, existing, sourceDominant, context);

                        master.put(key, element);

                        if (!pending.isEmpty()) {

```

### Existing object replication

Existing object replication as detailed [here](https://aws.amazon.com/blogs/storage/replicating-existing-objects-between-s3-buckets/) can be enabled by passing `existing-objects` as a value to `--replicate` flag while adding or editing a replication rule.

	--remote-bucket http://minio:minio123@127.0.0.1:9004/bucket \
	--replicate "existing-objects,delete,delete-marker,replica-metadata-sync"
sleep 1

echo "adding replication rule for b -> a : ${remote_arn}"
./mc replicate add siteb/bucket/ \
	--remote-bucket http://minio:minio123@127.0.0.1:9001/bucket \
	--replicate "existing-objects,delete,delete-marker,replica-metadata-sync"
sleep 1

### Existing object replication

        UrlQueueImpl<Long> existing = new UrlQueueImpl<>();
        existing.setUrl("https://example.com/existing");
        existingQueue.add(existing);

        UrlQueueImpl<Long> visitedUrl = new UrlQueueImpl<>();
        visitedUrl.setSessionId(sessionId);
        visitedUrl.setUrl("https://example.com/existing");

        client.admin().indices().prepareDelete(indexName).execute().actionGet();
        suggester.shutdown();
    }

    /**
     * Test getIndicesForAlias method with non-existing alias.
     * Verifies that the method returns an empty list for non-existing alias.
     */
    @Test
    @SuppressWarnings("unchecked")
    public void testGetIndicesForAlias_nonExistingAlias() throws Exception {

        assertEquals(flags1, result, "Should return first occurrence");
    }

    /**
     * Test get method with non-existing type
     */
    @Test
    @DisplayName("Get should return null for non-existing type")
    void testGetNonExistingType() {
        List<AvPair> pairs = new LinkedList<>();
        pairs.add(new AvFlags(0x12345678));
