> Though it is bad practice, it is possible that an object can return null from its toString() method. ObjectModel.toBoolean(Object) \[[Line 161|https://github.com/apache/sling-org-apache-sling-scripting-sightly-runtime/blob/master/src/main/java/org/apache/sling/scripting/sightly/render/ObjectModel.java#L161]\] calls .trim() on a potentially null object.
> This causes a difficult to troubleshoot, deeply nested, and cryptic exception to be raised. If object.toString() returns null, then it should be treated the same as nearly the rest of HTL, where null is considered "falsey". Doing so will save hours of difficult troubleshooting.
