> We recently upgraded from CXF 3.1.9 to 3.5.5 and after upgrade encountered this bug.
> Specifically we have some {{javax.ws.rs.container.ContainerRequestFilter}} implementations that are built using {{@Produces}} methods on our base {{javax.ws.rs.core.Application}} class. Since the upgrade we have discovered that these filters are being added to the request interceptor chain twice.
> After debugging I found that all CDI managed beans built by {{@Produces}} methods that use the {{@Provider}} annotation for discovery are now processed twice.
> It appears to me that the problem is in the current implementation of {{{}JAXRSCdiResourceExtension{}}}. This implementation has {{@Observes}} methods for both {{ProcessProducerMethod}} events and {{ProcessBean}} events - but {{ProcessProducerMethod}} extends {{ProcessBean}} so both of these handlers get called for each {{ProcessProducerMethod}} event fired by the CDI implementation. This means both handlers add the producer method to the list of {{providerBeans}} and the producer method is subsequently called twice when {{loadProviders()}} is called and two instances of the provider are passed to the {{{}JAXRSServerFactoryBean{}}}.
> I believe this behaviour was introduced by this commit:
