-------------------------------
> NPE in ObjectModel.toBoolean(Object) when object.toString() returns null

> Key: SLING-9314
> URL: https://issues.apache.org/jira/browse/SLING-9314
> Project: Sling
> Issue Type: Bug
> Components: Scripting
> Affects Versions: Scripting HTL Runtime 1.0.0-1.4.0, Scripting HTL Runtime
> 1.1.0-1.4.0, Scripting HTL Runtime 1.1.2-1.4.0
> Reporter: Paul Bjorkstrand
> Assignee: Radu Cotescu
> Priority: Major
> Fix For: Scripting HTL Runtime 1.2.4-1.4.0

> 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.
