AEM 6.5 Service Pack 19 installed, javax.servlet.include.query_string missing
We are in the process upgrading AEM 6.5.12 to 6.5.19. After installing service pack 19, in our code, request.getAttribute("javax.servlet.include.query_string") commands return null instead of query string information. It seems that all the javax.servlet.RequestDispatcher 's javax.servlet.include.* constants are now missing from the request.
I have looked through the service pack release notes (13-19) and found nothing about changes to the request or to javax.servlet.
Does anyone have any idea how or way this would change and what kind of remedy is available, either to get it back or some kind of work around?
