class Assignment { Class source, target; }

The following rule fails to match when target == java.lang.Object.class
rule ObjectIsAssignable
when
    Assignment( $t: target == (java.lang.Object.class) || target == source )
then
end

The following rule fails to match when target == source
rule ObjectIsAssignable
when
    Assignment( $t: target == source || target == (java.lang.Object.class) )
then
end

The error does not occur if the binding ($t) is omitted.
