Description

The properties component spi has a setOverrideProperties that allow to use an arbitrary Properties object so it is possible that the properties it holds are not of type string.

In case the properties component is asked to resolve a non string property, then it will fail as DefaultPropertiesLookup uses Properties::getProperty [¹] which returns null in case of the requested property is not of type string.

The error is a little bit misleading as it states:

because of PropertiesComponent with name properties must be defined in CamelContext to support property placeholders. Property with key [the.body] not found in properties from text: in.body == {{the.body}}
