Description

WireTap processing does not work when the route uses NoErrorHandler. This behaviour appeared since Camel 3.7.0. I'm using JDK 11.

Here is an example route. The mock:wiretapTarget is not called and a warning is shown in the logs. I was able to reproduce the problem also with a JUnit test (please see the attachment).
 

       from("direct:routeWithNoErrorHandler")
                .errorHandler(noErrorHandler())
                .wireTap("mock:wiretapTarget");
