Nathan Bubna updated VELOCITY-620:
----------------------------------

    Attachment: Velocity620TestCase.java

For the first of your examples, 1.6-dev (with the standard velocity.properties) works fine, and for the second, i get this helpful error:

org.apache.velocity.exception.ParseErrorException: Encountered "=" at line 1, column 9 of #if ($x = "a")
#end
Was expecting one of:
    <RPAREN> ...
    "-" ...
    "+" ...
    "*" ...
    "/" ...
    "%" ...
    <LOGICAL_AND> ...
    <LOGICAL_OR> ...
    <LOGICAL_LT> ...
    <LOGICAL_LE> ...
    <LOGICAL_GT> ...
    <LOGICAL_GE> ...
    <LOGICAL_EQUALS> ...
    <LOGICAL_NOT_EQUALS> ...

> The following incorrect velocity usage:
> #macro(foo $a)
>   blaa
> #end
> #foo("b" "c")
> or ...
> #if ($x = "a")
> #end
> will create the obscure error message in the exception:
> > Bad Reference "null" in /foo.vm:18
