Marking EAP 7 as being affected but at a low impact, although some artifacts are shipped that contain what we have determined as being vulnerable code but the use of these artifacts in EAP does not expose the vulnerable behaviour i.e. does not result in excessive CPU usage and will not result in a DoS.
