WSDLGetInterceptor throws NullPointException when using
EndpointSelectionInterceptor
------------------------------------------------------------------------------------
Key: CXF-3585
URL: https://issues.apache.org/jira/browse/CXF-3585
Project: CXF
Issue Type: Bug
Components: Core
Affects Versions: 2.4
Reporter: David Liu
Hi,
It looks like WSDLGetInterceptor assumes that the current exchange has one
Endpoint, however, there is the case we can use EndpointSelectionInterceptor to
get the Endpoint later, so the Endpoint could be null and which causes
NullPointException .
e.g. WSDLGetInterceptor expects one Endpoint,
{code}
class WSDLGetInterceptor {
//cannot have two wsdl's being written for the same endpoint at the same
//time as the addresses may get mixed up
synchronized (message.getExchange().getEndpoint()) { <--
NullPointException
...
{code}
However, the Endpoint is null at this moment and it will be set in
EndpointSelectionInterceptor later.
{code}
public void handleMessage(Message message) throws Fault {
Exchange ex = message.getExchange();
Set<Endpoint> endpoints =
CastUtils.cast((Set)ex.get(MultipleEndpointObserver.ENDPOINTS));
Endpoint ep = selectEndpoint(message, endpoints);
if (ep == null) {
return;
}
ex.put(Endpoint.class, ep);
{code}
