BeanDeserializer fails to deserialize if element name is "class"
----------------------------------------------------------------
Key: AXIS-1809
URL: http://issues.apache.org/jira/browse/AXIS-1809
Project: Axis
Type: Bug
Components: Serialization/Deserialization
Versions: current (nightly)
Environment: Linux, Sun J2SE 1.4.2_06-b03
Reporter: Makoto Kishimoto
Priority: Minor
When deserializing xsd:any type element, if the top level element's
element name is "class", BeanDeserializer throws NullPointerException.
Because "class" is a property name of any Beans have, logic of near of
following code looks fail.
BeanDeserializer#onStartChild()
----
if (propDesc == null) {
// look for a field by this name.
propDesc = (BeanPropertyDescriptor) propertyMap.get(localName);
}
// try and see if this is an xsd:any namespace="##any" element before
// reporting a problem
if (propDesc == null) {
// try to put unknown elements into a SOAPElement property, if
// appropriate
propDesc = getAnyPropertyDesc();
if (propDesc != null) {
try {
