Why Normal Exception...

In the computer sciences, an exception is a special condition that disrupts the intended flow of the application.  For example, entering a number when an alpha character is expected would throw an exception within the code.  Generally, when an exception is thrown, the programmer will "catch" it, and handle the exception gracefully, i.e. displaying an informative message and either stopping the program, or allowing the user to correct his/her mistake. Upon starting my professional career, my colleagues and I were given a few projects to redesign and in some cases, reinvent.  During code analysis, we came across many breaks in the code where the application was trying to "catch" an exception.  During this analysis, we noticed that the code wasn't really handling any exceptions, and any exceptions that were thrown, were just ignored and allowed the program to continue.  When we read through some documentation and comments, we came across many instances describing these cases as "Normal Exceptions".  The phrase in itself is an oxymoron, one like a "Healthy Sick Person", or a "Working Broken Device".
