Charts - JSONPath error

[sandoeg]

The following JSON formatted messages is being published on topic = home/environment on test.mosquitto.org.

{
"humidity": 53.57,
"pressure": 29.96,
"temperature": 77.38,
"timestamp": "Tue Sep 26 10:14:02 2017"
}

I am creating a Chart by selecting the topic from the Received messages summary, selecting Charts, then Show payload values for this topic.
I change Type = Payload to Type = JSONPath
I edit the Value expression = $.temperature

Response:
I get no plotted values.
I get a "java.lang.ClassCastException:java.lang.Double cannot be cast to [C" error.
