Description

I used strict reference checking for the first time and discovered that it throws exceptions even for quiet references.

<input class="signupInput" type="text" id="StxtFirstNames"
name="firstName" value="$!user.firstName"/>

org.apache.velocity.exception.MethodInvocationException: Variable
$user has not been set at layout/slide_login.vm[line 13, column 117]

This doesn't make sense to me. If a template author designates a reference as quiet, it's explicitly not an error. We're preventing the use of this convenient feature.

It's not a hard change to fix this. Does it break backwards compatibility if we change this?

Incidentally, there's an identical problem for InvalidReferenceEventHandler. I'll file a separate issue.
