Thanks for reporting. Fixed in CVS now.

Two new kinds of components (XSFacet & XSMultiValueFacet) were added to the XML Schema API some time ago, but the array in SchemaGrammar was't updated to reflect this change.

       Type: Bug

     Status: Resolved
   Priority: Major

Description:
I have this exception 
java.lang.ArrayIndexOutOfBoundsException: 15
	at org.apache.xerces.impl.xs.SchemaGrammar.getComponents(Unknown Source)
	at xs.QueryXS.traverse(QueryXS.java:323)
	at xs.QueryXS.main(QueryXS.java:127)

What I am doing is as follows:

XSNamespaceItemList nsItemList = model.getNamespaceItems();
if (nsItemList != null)
   XSNamespaceItem nsItem = nsItemList.item(0);
   XSNamedMap nmap = nsItem.getComponents((short)
                     XSTypeDefinition.COMPLEX_TYPE);


-------
After examining the xerces source files, I notice the error occurs at
line 811 of org.apache.xerces.impl.xs.SchemaGrammar. It tries to check for GLOBAL_COMP with an index larger than the declared array.

    public synchronized XSNamedMap getComponents(short objectType) {
        if (objectType <= 0 || objectType > MAX_COMP_IDX ||
            !GLOBAL_COMP[objectType]) {
            return null;
        }
        ...

Hope the information is helpful
