Claus Ibsen reassigned CAMEL-26017:
-----------------------------------
Assignee: Claus Ibsen
> camel-paho - the paho and paho-mqtt5 producers fail with a
> NullPointerException for a body that does not convert to bytes
> -------------------------------------------------------------------------------------------------------------------------
>
> Key: CAMEL-26017
> URL: https://issues.apache.org/jira/browse/CAMEL-26017
> Project: Camel
> Issue Type: Bug
> Components: camel-paho, camel-paho-mqtt5
> Affects Versions: 4.18.0, 4.22.0, 4.23.0
> Reporter: Claus Ibsen
> Assignee: Claus Ibsen
> Priority: Minor
> Fix For: 4.24.0
>
>
> The paho and paho-mqtt5 producers read the body with
> {{getBody(byte[].class)}} and pass it to {{new MqttMessage(payload)}}
> ({{PahoProducer}}, main 56aa5f4970a6, lines 59-61; {{PahoMqtt5Producer}},
> lines 51-53). For a body that does not convert to bytes, such as a Map, a
> POJO, a number or no body, the payload is null and the Paho client throws a
> NullPointerException with no message, which does not say what is wrong.
> Checked on 4.24.0-SNAPSHOT with {{camel run}} against {{camel infra run
> mosquitto}}: a Map, a POJO, an Integer and no body fail with
> {{java.lang.NullPointerException}} with an empty message, for paho and for
> paho-mqtt5. Text, bytes, a stream and a file are sent.
> *Proposed change*: read the body with {{getMandatoryBody(byte[].class)}},
> which fails with an InvalidPayloadException that names the type of the body.
