Every developer is occasionally guilty of writing code knowing it’s not perfect, but is good enough for now. In fact, this is often the correct approach. As Voltaire wrote,

I've just finished tuning a client's application where one of the items on the table was to find the source of calls to System.gc(). Using Censum made easy work of understanding the source of the calls.

Validating Oracle Java Cloud Service HA
One of my favorite applications from my Sun Java System Application Server days was the Cluster JSP Sample Application.
