CAS 5.3 error defining custom login exceptions

[Yan Zhou]

Hello, 

CAS 5.3.3 overlay on tomcat8.  I wish to display an error message on CAS login that says you have one more attempt or two more attempts to login, before get locked out.

I defined two new exception classes below in cas.properties.

cas.authn.exceptions.exceptions=org.apereo.cas.authentication.exceptions.OneMoreAttempLoginException,org.apereo.cas.authentication.exceptions.TwoMoreAttempLoginException

In message.properties, I provided the message.  When CAS starts up, I got this error. 

What am I missing?  Is this not the correct way to define a list of exception classes?

Thx!
