ConcurrentModificationException from getting features
Hi guys
I need a little help here.
We have a J2EE application running on JBoss AS 7.1.1 with JBossWS Native Stack 4.0.2.GA(due to backward compatibility problems). The application connects to an apache cxf web service running on tomcat using a Jax-WS client.
Recently we started getting ConcurrentModificationException from calling the service on our production environment (strack trace at the bottom).
The javax.xml.ws.Service object itself is cached in a proxy class like that:
if (service == null) {
try {
service = Service.create(wsdlURL, serviceName);
} catch (Exception e) {
.......
}
}
return service;
We are using MTOM feature when getting the port like that:
Service service = serviceProxy.getService();
if (service != null) {
T client = service.getPort(clazz, new javax.xml.ws.soap.MTOMFeature( ));
}
return client;
Any clues what could the problem? Is it possible that using features makes Service not thread safe?
I'd appreciate any info regarding the matter.
Cheers
Tom
