Dan, Thanks for sharing your pain. You should check out Jalopy on SourceForge. It is a code formatter and code inspector. It allows you to format your java code according to your organization's conventions and also inspect it for some of the items in Joshua Bloch's Effective Java book. The code inspector capability includes detecting empty catch and finally clauses. There are integrations with several IDE's and Ant. We use Jalopy to format and catch bad programming practices and integrate it as part of the build process.

I know that this might be obvious, but I am telling you all just so that you can learn from my pain. Because of time pressure, I accidently left an caught exception in the following state: catch (Exception e) { // TODO: do something with me } For the last couple of days the application server has been coming crashing down. The problem was that this particular exception was being thrown as the result of a StackOverflow error. When the exception was silenced, the execution would go back around and throw the StackOverflow error again inside a loop. Eventually, memory would become expended and the app server would die. But because the error is totally silenced, no reason is given for the crash because the app server didn't receive any messages. At the very, very least, log the error. That will give you an inkling of an idea as to where the server might be dying. Even if there is no way you think that the code you wrote would lead to a StackOverflow (or some other accumulating problem), do it anyway. Point is, you are better safe then sorry. I am an idiot for leaving that exception in that state, but at least I learned my lesson.
