We are using Crap4J for years now within our JAVA projects and it's the only tool which identifies "dangerous" code. Even the Jenkins/Hudson integration is nice! All code coverage tools will deliver lot's of false positives. I don't have to test a method like:public Value get Value(){ return value;}That's common sense, but a tool like Code Pro or Ja Co Co forces me to write dumb tests.

Only Crap4J rocks that way, even it has not been modified since a couple of years. Now it's time to do something, because JAVA7 code is not running with Crap4J!.
