I learnt about this project thanks to Brian Goetz who at JavaOne was wearing a fetching FindBugs t-shirt. I tried it today, running it on the ActiveMQ codebase and found some bugs! It totally rocks! Thanks Brian!
I'm now a life long findbugs user. FWIW if you're using maven to build your project, install the plugin and just type
If you're not using Maven just hack with your build.xml to use the FindBugs Ant task.
BTW am at OSCon and really enjoying myself - its a great conference so far. If you're at OSCon, I'm giving a Groovy talk tomorrow afternoon (wednesday), do pop by and say hello.
