ParamConverterProvider NullPointerException on methods with no params

If we have a method declared like this:

@GET
@Path("/me/operations")
public List<String> getUserOperations() throws Exception; 

And we have a ParamConverterProvider registered.

We get a NullPointerException in this line:

org.jboss.resteasy.microprofile.client.ProxyInvocationHandler.invoke(ProxyInvocationHandler.java:90)

Link to code: https://github.com/resteasy/resteasy/blob/237f9ac028c1070af325041ff2e34017a4201bc1/resteasy-client-microprofile-base/src/main/java/org/jboss/resteasy/microprofile/client/ProxyInvocationHandler.java#L90

"args" can be null, so we need to check that.

Thanks
