All exception constructors should take a String parameter

I've spent several days in code reviews. I kept seeing Exception classes with empty constructors, and that just drives me nuts. I also saw exception constructors taking only a Throwable. That drives me nuts almost as bad. After a few days I realized what the programming recommendation should be:

• All exception constructors should take at least a String parameter

They may take more than a String, of course, such as a Throwable, or an extra int, but there must be at least a String parameter.

Oh, and programmers that write

   throw new FooException("");

should be flogged.
