URL: https://github.com/apache/camel/pull/9510#issuecomment-1464994118

   I helped debugging a production issue where some code was refactored from a route definition (`from(...).setHeader("name", constant("value")`) to a processor (`exchange.getMessage().setHeader("name", constant("value")`).  Where previously the header was set to the correct value, after the refactor the header was being set to `constant{value}`.
   
   The `setHeader` and `setProperty` methods on Java DSL have overloads for `Expression` and `Supplier` to resolve the values, where the methods on the message / exchange don't.
