[jira] [Resolved] (CXF-4534) SortedMap is returned as HashMap

     [ https://issues.apache.org/jira/browse/CXF-4534?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Daniel Kulp resolved CXF-4534.
------------------------------

       Resolution: Fixed
    Fix Version/s: 2.6.3
                   2.5.6
         Assignee: Daniel Kulp


This should now be fixed.  It would be great if you could verify with tomorrows snapshots.

> We have recently upgraded to 2.6.2 and revisit our test suite. Looks like all bugs submitted by use have been fixed. Very impressive, thanks a lot.
> In our test suite there is a bug that has not been submitted in JIRA. A discussion about that bug can be found at
> http://comments.gmane.org/gmane.comp.apache.cxf.user/12388
> I decided to submit this bug anyway for documentation purposes.
> The problem:
> ------------
> The problem is when the interface declares a SortedMap as an argument or as a returned value. Here is the relevant snippets.
> Interface
> ---------
> {code:java}
>     // fail -- throws exception in the server
>     public boolean testSortedMapArgument(SortedMap<Integer, Integer> map);
>     // fail -- puts data into a hashmap instead of a SortedMap
>     public SortedMap<Integer, Integer> testSortedMapResult();
>     // fail -- puts data into a hashmap instead of a SortedMap
>     public Map<String, SortedMap<Integer, Integer>> testDirectComplexTreeMapResult();
> {code}
> Implementation
> --------------
> {code:java}
>     @Override
>     public boolean testSortedMapArgument(SortedMap<Integer, Integer> map) {
>         final Class map_class = map.getClass();
>         final Collection<Class> klasses = Arrays.asList(map_class.getClasses());
>         log.info(String.format("Classes of %s are %s", map_class, klasses));
>         return klasses.contains(SortedMap.class);
>     }
>     @Override
>     public SortedMap<Integer, Integer> testSortedMapResult() {
>         final SortedMap<Integer, Integer> result = new TreeMap<Integer, Integer>();
>         result.put(1, 3);
>         result.put(0, 2);
>         return result;
>     }
>     @Override
>     public Map<String, SortedMap<Integer, Integer>> testDirectComplexTreeMapResult() {
>         final Map<String, SortedMap<Integer, Integer>> result = new HashMap<String, SortedMap<Integer, Integer>>();
>         final TreeMap<Integer, Integer> map1 = new TreeMap<Integer, Integer>();
>         map1.put(1, 3);
>         map1.put(0, 2);
>         result.put("key1", map1);
>         return result;
>     }
> {code}
> Test Client:
> ------------
> {code:java}
>     @Test
>     public void testSortedMapArgument() {
>         final SortedMap<Integer, Integer> map = new TreeMap<Integer, Integer>();
>         map.put(1, 3);
>         map.put(0, 2);
>         Assert.assertTrue(TestServiceFactory.getService()
>                 .testSortedMapArgument(map));
>     }
>     @Test
>     public void testSortedMapResult() {
>         final Class map_class = ((Object) TestServiceFactory.getService()
>                 .testDirectComplexTreeMapResult()).getClass();
>         final Collection<Class> klasses = Arrays.asList(map_class.getClasses());
>         log.info(String.format("Classes of %s are %s", map_class, klasses));
>         Assert.assertTrue(klasses.contains(SortedMap.class));
>     }

>         log.info(String.format("Classes of %s are %s", map_class, klasses));
>         Assert.assertTrue(klasses.contains(SortedMap.class));
>     }
> {code}
> The result:
> -----------
> In cases 2 and 3 I get a hashmap instead of a SortedMap. This is very dangerous since it changes program semantics in a very subtle way.
> In case 1 I get an exception. Here is the server side part:
> {code}
> WARNING: Application {http://iface/}TestInterface#{http://iface/}testSortedMapArgument has thrown exception, unwinding now
> org.apache.cxf.interceptor.Fault: argument type mismatch while invoking public abstract boolean iface.TestInterface.testSortedMapArgument(java.util.SortedMap) with params [{0=2, 1=3}].

> Expected result:
> ----------------
> To safely transfer a SortedMap both ways.
> I would understand if due to WSDL  constraints reliably transferring a sortedMap is not possible. What it would be nice is at least during the deploy time an error / warning is issued stating that fact.
> Right now we are getting incorrect results in a silent way or a the best case an exception at run time.
