Problem Description:
Following up on Bug 4197164, in order to support CORS preflight requests, every endpoint in the API must define an OPTIONS handler.  Some endpoints can include optional path parameters such as "/users" and "/users/123".  ColdFusion's REST support includes the ability to use regular expressions in restPath definitions which should be able to handle this and, so as not to have to create separate OPTIONS handlers for both of these formats, I tried to do just that.  Unfortunately, it is not working as expected.

Steps to Reproduce:
1) Create an endpoint such as:

<cfcomponent rest="true" restpath="/users" produces="application/json">
	<cffunction name="corsPreflight" access="remote" returntype="void" httpMethod="OPTIONS" restPath="{id:.*}">
		<cfargument name="id" type="string" required="false" restargsource="Path" />

		<!--- Do CORS stuff here --->

2) Send an OPTIONS request to this endpoint such as "/accounts/123".  This will succeed.
3) Send an OPTIONS request to this endpoint such as "/accounts".  This should succeed but will fail.

Actual Result:

Expected Result:

Any Workarounds:
Create two separate OPTIONS handler functions, one accepting the rest path parameter and one not such as:
	<cffunction name="corsPreflight" access="remote" returntype="void" httpMethod="OPTIONS">

	<cffunction name="corsPreflightWithId" access="remote" returntype="void" httpMethod="OPTIONS" restPath="{id:.*}">

HariKrishna, Please reopen this bug. This is not a duplicate of CF-4197195. CF-4197195 is a problem with the order of different endpoint handling methods. This bug, CF-4197166, is a problem with CF's (or Jersey's) regex support in endpoint handler methods. The examples I gave for the two bugs were similar, but the two bugs are very different. Thanks, Mosh
