21  * Schema2BeansRuntimeException
22  * I'd rather this class didn't exist. I wanted to change the API to throw
23  * proper exceptions, but this is difficult to do with so many users of
24  * this library. This class exists to fill in where I found it
25  * difficult to throw a normal Schema2BeansException, since anything
26  * that inherits from RuntimeException doesn't have to be caught.
27  *
28  * With that being said, there are a few times when a RuntimeException
29  * would be approbate enough, but I used Schema2BeansRuntimeException
30  * as it has more features.
