An empty JSON, such as "{}", causes the json uml processor to fail.

Is this a bug?

Hello C.,

Yes, it is a bug.

@PlantUML: we observe the same issue with an empty tab, like:

@startjson
[]
@endjson

→ http://www.plantuml.com/plantuml/uml/SoWkIImgoIhEp-EghkLoICrB0R41

And FYI, the issue occurs only on the first level, for other level that is OK:

@startjson
{
"empty_tab": [],
"empty_list": {}
}
@endjson

Regards,
Th.
