> The following regular expression works fine (for an elephant maintenance system at a zoo):
> @Path("/{id:\\d+}")
> public Person getElephantSubresource(@PathParam("id") int id);
> However, placing spaces around the colon delimiter as follows:
> @Path("/{id : \\d+}")
> public Person getElephantSubresource(@PathParam("id") int id);
> ... causes these exceptions to occur at service deployment time:
> org.springframework.beans.PropertyBatchUpdateException; nested PropertyAccessExceptions (1) are:
> PropertyAccessException 1: org.springframework.beans.MethodInvocationException: Property 'serviceBeans' threw exception; nested exception is java.util.regex.PatternSyntaxException: Illegal repetition near index 0
