Jrockit mission control supports an "exception count" based on exception type.
I have found the approach of just counting the total number of exception completely useless. Mainly because there are methods that throw exceptions as part of the normal flow. For example, Class.forName() is commonly used to test whether or not a certain class is on the classpath. And most developers will cringe whenever they see an exception count>0 for an application they think is bug free.
