> JNDI lookup for a datasource on EAP 6.0 returns an instance of WrapperDataSource [1] and since it doesn't override JBossWrapper.getWrappedObject() [2] which is in the super class, unwrap() always returns null. 
> WrapperDataSource should override getWrappedObject() as stated in the javadoc to return the underlying datasource.
> With the current implementation, the following code always throws exception: 
> {code:java} 
>     Context ctx = new InitialContext();
>                 DataSource ds = (DataSource)ctx.lookup("jboss/datasources/ExampleDS");
>                 OracleDataSource unwrapped = null;
>                
>                 if (ds instanceof WrapperDataSource) {
>                         WrapperDataSource wrapper = (WrapperDataSource) ds;
>                         try {
