Due to checked exceptions, we can have some problems in production having all exceptions caught in the right place and logged correctly.
I wonder if there is some opensource tool to help with auditing these problems.
For example, is there some AOP tool that would intercept all exceptions thrown and see if they are re-thrown, wrapped or logged? This would help identify the bad catches.

When an exception is thrown using the throw keyword, the flow of execution of the program is stopped and the control is transferred to the nearest enclosing try-catch block that matches the type of exception thrown. If no such match is found, the default exception handler terminates the program.
Java Exception Handling is a mechanism to handle runtime errors such as ClassNotFoundException, IOException, SQLException, RemoteException, etc. Exception is an unwanted or unexpected event, which occurs during the execution of a program, i.e. at run time, that disrupts the normal flow of the program's instructions.
Using the Throws keyword Throws is a keyword used to indicate that this method could throw this type of exception. The caller has to handle the exception using a try-catch block or propagate the exception. We can throw either checked or unchecked exceptions.
If you've decided that you would like to take the AOP route, the Spring Framework provides an easy to use AOP framework. Essentially, like much of Spring, you would use a combination of a xml config file and some java code to define the AOP functionality you are looking for.
In your case, I believe you would be looking to define an 'After Throwing Advice', in which you would of course have access to the exception thrown.
A good place to start in terms of documentation is the AOP Chapter in the Spring docs: http://static.springsource.org/spring/docs/2.5.x/reference/aop.html
Oh, and I believe all Spring projects are open source as well =)
