Virtual directory mapping is failing in forms 12c

I have some custom JAR files exists in my own directory. I created virtual directory mapping to my directory using the following setup in forms.conf

AliasMatch /forms/test/(..*) "C:\new/$1"

WLExcludePathOrMimeType /forms/test/

But it is not able to access the JAR files and failing with error that "HTTP response code: 403".

Then I followed "https://community.oracle.com/thread/3890697" thread and added following lines of code to forms.conf, still it is failing with same error.

RewriteRule ^/forms/test/(..*) /test/$1 [PT]

AliasMatch ^/test/(..*) "C:\new/$1"

Forms version: 12.2.1.2.0

OS: Windows Server 2012R2

WLS: 12.2.1.2.0

JDK: 1.8U121

Can someone guide to configure the virtual directory mapping.
