[Resteasy-developers] MIME type image/gif ?

[<Juergen.Zimmermann@HS-Karlsruhe.de>]

I have the following method which works fine using Jersey. After switching
to RESTEasy 1.0beta9 I get the stacktrace below. Any hint is appreciated!

	@GET
	@Path("/images/{image}")
	@Consumes
	@Produces("*/*")
	public Response findImage(@PathParam("image") String image) {
		...
		final File file = new File(BASE_PATH + image);
		if (!file.exists()) {
			return Response.status(NOT_FOUND)
			               .type(TEXT_PLAIN)
			               .entity("... error message ...")
			               .build();
		}

		final String contentType = new
MimetypesFileTypeMap().getContentType(file);
		return Response.ok(file, contentType).build();
	}


The stacktrace:

ERROR core.SynchronousDispatcher - Failed executing GET
/kundenverwaltung/images/java.gif
