In the vast majority of cases you should not use the “catch all” handler as a means of dealing 

with exceptions. It is normally better to deal individually with the exceptions that your code can 

generate. The inappropriate use of the “catch all” handler can lead to situations in which errors 

that would otherwise be caught during testing are masked. It is also difficult to correctly handle 

all types of exceptions with a single hander. That said, a “catch all” handler might be appropriate 

in certain specialized circumstances, such as in a runtime code analysis tool.
