BugTrap is a highly modularized J2SE library that essentially provides a simple interface to the "hosting" application offering a couple of methods for the logging of runtime incidents. One of the core features of BugTrap is the ability to sort out equal application incidents based on the provided stacktrace or the incident/error message - further helpful capabilities can be bound using plugins.
Please note that BugTrap resides in your application; it is not a post mortem debugger.
BugTrap and its plugins are part of the BugWerk project. This page belongs to the release 1.3.
