Description

This is very similar to GROOVY-4604 and GROOVY-4601.

Groovy code:

import javax.ws.rs.GET
import javax.ws.rs.Path

@Path('/')
class GroovyService {
    @GET
    @Path('{id:[^.]\\.[^.]}')
    String getIt(String id) {
        return id;
    }
}

Results in stub:

import java.lang.*;
import java.io.*;
import java.net.*;
import java.util.*;
import groovy.lang.*;
import groovy.util.*;

@javax.ws.rs.Path(value="/") public class GroovyService
  extends java.lang.Object  implements
    groovy.lang.GroovyObject {
;
public  groovy.lang.MetaClass getMetaClass() { return (groovy.lang.MetaClass)null;}
public  void setMetaClass(groovy.lang.MetaClass mc) { }
public  java.lang.Object invokeMethod(java.lang.String method, java.lang.Object arguments) { return null;}
public  java.lang.Object getProperty(java.lang.String property) { return null;}
public  void setProperty(java.lang.String property, java.lang.Object value) { }
@javax.ws.rs.GET() @javax.ws.rs.Path(value="{id:[^.]\.[^.]}") public  java.lang.String getIt(java.lang.String id) { return (java.lang.String)null;}
}

Which results in error:

GroovyService.java:[17,53] error: illegal escape character
