>          Issue Type: Bug
>          Components: databinding
>    Affects Versions: 1.1

> I want to create a service which return an object containing a List:
> The object to return:
> public class Container {
>   private List myList = new ArrayList();
>   public List getList() {
>     return myList;
>   }
> }
> The service (pojo) :
> public class MyService {
>   private Container container = new Container();
>   public Container getContainer() {
>     container.getList().add("a test");
>     return container;
>   }
> }
> When I try to access the service I receive an Exception:
> Caused by: java.lang.IllegalArgumentException: null rcl
>         at org.codehaus.jam.internal.reflect.ReflectClassBuilder.<init>(ReflectClassBuilder.java:47)
>         at org.codehaus.jam.provider.JamServiceFactoryImpl.createBuilder(JamServiceFactoryImpl.java:173)
> I checked the code, and I saw in the class org/apache/axis2/databinding/utils/BeanUtil,
The only object I can use to send a list is the ArrayList. Why ?
> I change the isArrayList method in org/apache/axis2/databinding/typemapping/SimpleTypeMapper
to detect a java.util.List instead of just the ArrayList and it works fine. So why limit to
ArrayList (and not just Collection)?
> I think there is an other bug which return the IllegalArgumentException in org.codehaus.jam.internal.reflect.ReflectClassBuilder.java:
> In the method getPullParser of the class BeanUtil, there is no check on what returns
beanObject.getClass().getClassLoader() before doing the addClassLoader.
> Some implementations may use null to represent the bootstrap class loader. This method
will return null in such implementations if this class was loaded by the bootstrap class loader.
So that explain why the error is "null rcl".
> Thanks,
> Benoit
