When failing to authenticate by the Login portlet, it prints an exception to the log

To reproduce,

1. Startup Liferay,
2. Login using a bad user\password combination
3. Log will have an authentication exception

This is new to 6.1, older versions did not print an exception when failing to log in. Given the frequency of mistyping my own password I would assume in a production environment this would dirty the log with useless noise.
