Description
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.
Here is the stack trace for reference:
