Error when parsing empty/flat array context

When trying to parse JSON with nested arrays, the context works as designed. Ie.

Context: $.results.*

{
    results: [
        {
            key: 'value',
        }
    ]
}

But I get an error when I attempt to parse a flat array with an empty context. Ie.

Context: $.*

{
    key: 'value',
}

which results in the following error:

An AJAX HTTP error occurred. HTTP Result Code: 500 Debugging information follows. Path: /batch?id=59&op=do StatusText: Service unavailable (with message) ResponseText: Recoverable fatal error: Argument 1 passed to FeedsJSONPathParser::invokeHook() must be of the type array, boolean given, called in /feeds_jsonpath_parser/FeedsJSONPathParser.inc on line 80 and defined in FeedsJSONPathParser->invokeHook() (line 433 of /feeds_jsonpath_parser/FeedsJSONPathParser.inc).

It seems that the parser expects a context as an array.
