> Key: CXF-2180
> URL: https://issues.apache.org/jira/browse/CXF-2180
> Project: CXF
> Issue Type: Bug
> Components: Core, REST
> Affects Versions: 2.2
> Reporter: Holger Delfs
> Assignee: Daniel Kulp
> Fix For: 2.1.5, 2.2.1

> When using a JAX-RS proxy client with the spring bean
> <jaxrs:client id="subscriberService" serviceClass="sample.SubscriberService"
> address="http://localhost:8080/services/";>
> </jaxrs:client>
> where sample.SubscriberService is an interface, I would expect, that I don't
> need cglib in my classpath. Instead I get
> org.springframework.beans.factory.BeanCreationException with the following
> root cause:

> which I can only fix by including cglib in my Maven dependencies.
> The catch block in the static initializer of ProxyHelper lets me assume, that
> the usage of cglib features was intended to be optional. But if cglib.jar is
> not available, the class loading of CglibProxyHelper causes the error above.
> I suggest to either catch Throwable when calling CglibProxyHelper, or to
> avoid the class loading dependency on cglib classes within CglibProxyHelper.
