Description

I'm struggling with the PahoEndpointBuilder in both 3.2.0 and current 3.3.0-SNAPSHOT.
For testing purposes I have a simple route:

PahoEndpointBuilder endpointBuilder = paho (topic).brokerUrl (brokerUrl).userName (userName).password (password);
from (endpointBuilder).log ("${body}");

The startup of the application fails with the following exception causes:

Caused by: org.apache.camel.ResolveEndpointFailedException: Failed to resolve endpoint: paho:myTestTopicMandant9?brokerUrl=tcp%3A%2F%2Flocalhost%3A1883&password=xxxxxx&userName=test due to: Failed to resolve endpoint: paho:myTestTopicMandant9?brokerUrl=tcp%3A%2F%2Flocalhost%3A1883&password=xxxxxx&userName=test due to: There are 3 parameters that couldn't be set on the endpoint.

Curiously if I add a single line of code inbetween that creates the endpoint out of the builder it all works:

PahoEndpointBuilder endpointBuilder = paho (topic).brokerUrl (brokerUrl).userName (userName).password (password);
endpoint (endpointBuilder.getUri ());
from (endpointBuilder).log ("${body}");
