> Testing a simple example based on the Quickstart.java, using DefaultSecurityManager and PropertiesRealm with default user properties would successfully login users listed in the properties file, but fails with NPE on invalid usernames.
> I get NPE from SimpleAccountRealm.doGetAuthenticationInfo(AuthenticationToken token) method at this location:
>         if (account.isLocked()) {
>             throw new LockedAccountException("Account [" + account + "] is locked.");
>         }
> The variable account is null - as so it should be since it is not in the authorizationCache. I was testing for the behaviour when unknown users are trying to login.
> Seemingly a null test and return null would fix this issue, as the caller AuthenticationRealm.getAuthenticationInfo(AuthenticationToken token)  handles null return values.
