Radu Coravu created XERCESJ-1683:
------------------------------------
Summary: NullPointerException 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
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.
