> 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.
