Schema "groups" XmlSchemaObjectTable is filled using invalid HashMap keys
-------------------------------------------------------------------------

         Key: WSCOMMONS-24
         URL: http://issues.apache.org/jira/browse/WSCOMMONS-24
     Project: WS-Commons
        Type: Bug

  Components: XmlSchema  
 Environment: WS Commons XML Schema 1.0.2
    Reporter: Peter Hendriks


The XmlSchemaObjectTable  retrieved using XmlSchema.getGroups() is filled in 
SchemaBuilder by using the package scope collection variable instead of its 
public API. For groups and attribute groups a key of the wrong type is used 
(String instead of QName). 

As a result groups cannot be accessed using the public API, because you can 
only query using a QName, and the keys are only Strings. As a result groups 
cannot be read by key and the API is broken.

The issue can be worked around by using the getValues() method to search 
through all groups directly.

This should be very easy to fix and I am willing to provide a patch. The code 
is riddled with package scoped fields and methods. This is generally bad 
practice because of these kinds of problems. Please consider refactoring the 
code to more restrictive field/method scoping to have a cleaner API and prevent 
errors.
