> The safe-access array operator is not safe
> ------------------------------------------
>
> Key: JEXL-434
> URL: https://issues.apache.org/jira/browse/JEXL-434
> Project: Commons JEXL
> Issue Type: Bug
> Affects Versions: 3.4.0
> Reporter: Vincent Bussol
> Assignee: Henri Biestro
> Priority: Major
> Fix For: 3.4.1
>
>
> From the documentation:
> {code:java}
> The safe-access array operator (as in foo?[bar]) provides the same behavior
> as the safe-access operator and shortcuts any null or non-existent references
> along the navigation path, allowing a safe-navigation free of errors. In the
> previous expression, if 'foo' is null, the whole expression will evaluate as
> null. {code}
> Trying to use this syntax:
> {code:java}
> JexlEngine jexl = new JexlBuilder().safe(false).strict(true).create();
> final String src = "let foo = null; let value = foo?[bar]";
> final JexlScript script = jexl.createScript(src);
> assertNotNull(script);
> final Object result = script.execute(null);
> assertNull(result); {code}
> throws a Variable exception:
> {code:java}
> 1:29 variable 'foo' is null {code}
