Thanks Emmanuel. The document you pointed is very good. It solved my problem. For the people who are facing similar issues, I would like to tell my experience.First I tried list jars which do not need to scan. The situation did not improve much (maybe my app is small). Then I tried entropy. It significantly improved. Problem solved.
