Subject [jira] [Commented] (FREEMARKER-40) ClassIntrospector should detect public methods in non-public classes
Date Sat, 03 Dec 2016 16:13:58 GMT


Daniel Dekany commented on FREEMARKER-40:

Sadly, I can't make the error message more helpful either, because by the time it turns out
that the missing value (the {{null}}) will cause an error, the  left-hand operand value object
is already released. Without the left-hand operand I can't figure out why the subvariable
was null/missing. (I could prolong the life of the left-hand operand by putting it into the
{{Environment}} as {{lastDotLHO}} or something, but other than it makes the internal workings
of FM even more intimidating, it would prevent the immediate garbage collection of the left-hand
operand, which I guess it too dangerous a change with all the existing applications out there.)

>            Priority: Minor
> In ClassIntrospector.discoverAccessibleMethods, the assumption is made, that only public
classes can have accessible methods. This is plainly wrong: For example, a private object
might be implementing an interface.
> Freemarker should detect public gettters, and treat them as accessible. At the very least,
it should inform the user about the problem. A message like
>   "Key <propertyName> was not found on an instance of ..."
> should be replaced by
>   "Key <propertyName> was not found on an instance of ..."
>   "A possible reason is,that the class must be public."
> Thanks,
