Subject Re: Improving JAX-WS Performance

I think that the issue only occurs with services that use parameter
style WRAPPED and that have no @RequestWrapper annotation (or that
have a @RequestWrapper annotation but that don't package the wrapper
beans). I think that for WSDL-first, request wrappers are generated
automatically, so this would only apply to services implemented using
the code-first approach. Nevertheless this still covers a wide range
of use cases, so that this is a problem.
