Regular expressions in path parameters are raising errors in gwtp-rest-dispatch

[ias-dt]

We have a resource which uses regular expressions within the @path annotation like

@Path("search/{version: (\\d+\\.\\d+\\.\\d+\\.\\d+-\\d+)}{binary: (?:/([^/]*))?}")

In the generated RestAction implementation contains a constructor with:

super(httpParameterFactory, defaultDateFormat, HttpMethod.GET, "/search/{version: (\d+\.\d+\.\d+\.\d+-\d+)}{binary: (?:/([^/]*))?}");

addParam(Type.PATH, "version", version);
addParam(Type.PATH, "binary", binary);

So during compilation the compiler complains about invalid escape sequences because \d is not well escaped with two backslashes.

I thought that would be related to the ResourceDelegate stuff but now I think the problem is located in gwtp-dispatch-rest. Maybe the only thing to do is to remove the regular expression stuff in the path because it shouldn't be needed for filling in the parameters:

super(httpParameterFactory, defaultDateFormat, HttpMethod.GET, "/search/{version}{binary}");

addParam(Type.PATH, "version", version);
addParam(Type.PATH, "binary", binary);

This got out of my head, but we'll prioritize this issue in the current snapshot.
