> The call to canHandleQbForCbo() can result in an
> StringIndexOutOfBoundsException. The assumption in the code is that the msg
> can only be null and we handle that but the msg can also be an empty string
> if the *verbose* is set to false. This can happen if INFO Logging is not
> enabled. We need to handle that case.
