JavaJaxRS spec : formParam uses Attachment which is CXF specific

[RaphC]

Description

When using JavaJaxRS to generate API with an endpoint consuming a form to upload a file, the plugin translate file param data type in Attachment (org.apache.cxf.jaxrs.ext.multipart.Attachment) which is a CXF class. If we use another JaxRS implementation the compilation of generated API failed. The choice should be depends on JAX-RS implementation

:(. My question is : Is it possible to detect Jax-rs implementation, choose it and generation a dynamic datatype ?

Not that I'm aware of

I also came across this with #4091, currently the generated sources cause compilation errors as org.apache.cxf.jaxrs.ext.multipart.Attachment is not on the build path.

Please see #4509 for the fix of the org.apache.cxf.jaxrs.ext.multipart.Attachment reference, in fact this is not standardized yet (https://java.net/jira/browse/JAX_RS_SPEC-413), so I replaced it with InputStream to be at least not CXF-dependent for the JAXRS-spec.
