Yes, that would be an ideal long-term goal if anyone is willing to do it... but for now. I am hoping we can find a short-term quick turn around solution that fixes the root cause and get an official fix for all teams. (I'm going to re-read what Greg posted on that, once I start the code review with the patched changes). I'm keeping an eye on the test results from compwiztobe as well.

I believe one of the issues with this design is how closely it reflects the JAVA language version, where JAVA does not need to manage memory... hence the red arrows in the diagram (something I never used in my designs) show that objects are not being created and destroyed in the same place. This made it somewhat more difficult to track down the memory leaks. I think the redesign should be c++ based design which does abide by c++ conventions and have clean objects that manage memory properly... and then port this to JAVA... going in that direction... JAVA can simply ignore all calls to deletes, or interface them to do nothing... etc. Anyhow I just wanted to point this out for anyone else who is code reviewing.
