Major Description
AbstractRememberMeManager#getRememberedPrincipals will call the 'convertBytesToPrincipals' method even if the 'getRememberedSerializedIdentity' method call returns a null/empty byte array, resulting in the following stack trace. The 'convertBytesToPrincipals' method should only be called with a non null/empty byte array.
