            Description

            I've been running up against some memory problems with a much larger QA run and it appears the cmyk colou caches may behind the issue. They are unbounded and can be very large in size.

              I've been able to verify the slow memory leak when the caches are enabled and disabled. If users are running up against peformance issues when using ICC profiles then I suggest they try -Dorg.icepdf.core.cmyk.disableICCProfile=true which can offer significant improvements but at the cost of colour accuracy.
