> Key: XERCESJ-1279
> URL: https://issues.apache.org/jira/browse/XERCESJ-1279
> Project: Xerces2-J
> Issue Type: Bug
> Components: XML Schema 1.0 Structures
> Affects Versions: 2.9.1
> Environment: Windows, Sun JRE 1.6.00_03
> Reporter: Bill Michell
> Assignee: Arthur De Magalhaes

> Change 319073 introduced the class SubstitutionGroupHandler$OneSubGroup and
> the Hashtable fSubGroupB
> According to the documentation, the field has the following characteristics:
> // to store substitution group information
> // the key to the hashtable is an element decl, and the value is
> // - a Vector, which contains all elements that has this element as their
> // substitution group affilication
> // - an array of OneSubGroup, which contains its substitution group
> before block.
> Unfortuntately, addSubstitutionGroup() contains the following line:
> subGroup = (Vector)fSubGroupsB.get(subHead);
> This fails with a ClassCastException if the value for the key passed turns
> out to be a OneSubGroup[]
> The following lines of getSubGroupB() appear to ensure that a OneSubGroup[]
> is in the map:
> // Convert to an array
> OneSubGroup[] ret = new OneSubGroup[newGroup.size()];
> for (int i = newGroup.size()-1; i >= 0; i--) {
> ret[i] = (OneSubGroup)newGroup.elementAt(i);
> }
> // Store the potential sub group
> fSubGroupsB.put(element, ret);
>
