    Description

      ASTReference.java has some null check logic that does, summarized:

      if (value == null || value.toString() == null) {
      ...
      } else {
      ... output value.toString();
      }

      Note value.toString() being called twice.

      For strings and other primitives, this may not be a big deal, but I'm happily using Click, which puts full-fledged components into the velocity context that you render with "$componentName". Very slick. But now calling toString() multiple times isn't all that cool, both from perf and logic standpoints.

      I've got a patch if I can figure out how to upload it.
