Nenad Nesovanovic commented on CAMEL-14969:
-------------------------------------------
My assessment is that for the REST endpoint Camel Spring is automatically
creating producer and consumer route with the same name and as REST XML
discovered resources are discovered first, then Camel Context end up creating
them again from the routes definition created during the XML rest import.
If Camel Context XML is importing the same routes through the restContextRef
tag, then this issue does not occur, as rest definitions and endpoints are
created after the Camel Context is initialised.
Happy to provide more details if needed, but you should first go through the
attached logs and images and please pay attention to the variable watch list on
the images and debug stack trace that points out to the code lines and variable
values to prove that route definitions list ends up having two route
definitions for the single XML entry.
