For POST Request APIs - Trailing slash in the API endpoint removed

I am facing an issue where the trailing backslash is getting removed while the POST request is being sent through the apiman gateway.

I found the issue reported previously here: https://issues.jboss.org/browse/APIMAN-333. However, this was raised for the GET request and seems to be working fine for GET requests.

It will be great if this issue can be fixed once and for all types of requests and not particularly for POST requests.
