FYI. Since activiti 5.16, activiti starts use spring 4, but for some reason I have to use spring 3.2.* in my project, I did a simple test using activiti 5.16 and spring 3.2.7, it seems ok, but I am not hundred percent sure about this. And from the git commit history, it seems spring version was upgraded in the last commits of 5.16. Can some activiti project make sure about this? It is really important for me, thanks very much
