interceptFrom and from(Endpoint) don't work together
----------------------------------------------------
Key: CAMEL-3709
URL: https://issues.apache.org/jira/browse/CAMEL-3709
Project: Camel
Issue Type: Bug
Components: camel-core
Affects Versions: 2.5.0
Reporter: Søren Markert
Priority: Minor
When using interceptFrom(String) together with from(Endpoint), the below
Exception occurs during the routes building process. Looking at
RoutesDefinition.java:217 reveals, that the FromDefintion just created has no
URI. That causes the comparison to all the interceptFroms' URIs to fail. As far
as I can tell, the way to fix this would be to add
{{setUri(myEndpoint.getEndpointUri())}} in the constructor
{{FromDefinition(Endpoint endpoint)}}.
Below the stack trace, there is a unit test that demonstrates the issue. Until
it if fixed, it can be easily circumvented by adding the commented-out line,
and then change to {{from("myEndpoint")}}.
