Radu Coravu commented on XERCESJ-1683:
--------------------------------------
I do not have that sample, I changed the subject of the issue to better reflect
the problem. I guess I'm very used to adding NullPointerException-related
errors, but not on the Xerces project :)
> ArithmeticException in SymbolHash.get
> -------------------------------------
>
> Key: XERCESJ-1683
> URL: https://issues.apache.org/jira/browse/XERCESJ-1683
> Project: Xerces2-J
> Issue Type: Bug
> Components: SAX
> Reporter: Radu Coravu
> Priority: Major
>
> We use as XSModelImpl to iterate XML Schema components.
> One of our clients, on a schema that they did not provide obtained this NPE:
> {code}[ AWT-EventQueue-0 ] - java.lang.ArithmeticException: / by zero
> java.lang.ArithmeticException: / by zero
> at org.apache.xerces.util.SymbolHash.get(Unknown Source)
> at org.apache.xerces.impl.xs.XSModelImpl.getSubstitutionGroup(Unknown
> Source) {code}
> The NPE seams feasible if a SymbolHash with zero length is constructed and
> then queried for a value. Maybe this could be taken into account on your side.
