> Key: AMQ-3388
> URL: https://issues.apache.org/jira/browse/AMQ-3388
> Project: ActiveMQ
> Issue Type: Improvement
> Components: Transport
> Affects Versions: 5.4.1, 5.4.2, 5.5.0
> Reporter: Marcel Casado
>
> Addition of fields in commands used between clients and brokers in newer amq
> versions breaks easily the http transport that uses xstream for xml
> serialization.
> To make xstream more tolerant to this changes between versions in
> org.apache.activemq.transport.xstream.XStreamWireFormat we could add the code
> below so xstream ignores unknown fields :
> // Implementation methods
> //
> -------------------------------------------------------------------------
> protected XStream createXStream() {
> // return new XStream();
> return new XStream() {
> protected MapperWrapper wrapMapper(MapperWrapper next) {
> return new MapperWrapper(next) {
> public boolean shouldSerializeMember(Class definedIn,
> String fieldName) {
> return definedIn != Object.class ?
> super.shouldSerializeMember(definedIn, fieldName) : false;
> }
> };
> }
> };
> }
