-------------------------------

             Summary: Refine error message for incorrectly configured 
rememberMe cipherKey
                 Key: SHIRO-615
                 URL: https://issues.apache.org/jira/browse/SHIRO-615
             Project: Shiro
          Issue Type: Improvement
            Reporter: Rob Young
            Priority: Minor


Currently if the shiro configuration key 
*securityManager.rememberMeManager.cipherKey* is set incorrectly, an error is 
logged via a stack trace.  Unfortunately, this stack trace and associated error 
message do not provide much context and could be refined to indicate that the 
source of the error was the cipherKey.
