Amit Rokach commented on CAMEL-7884:
------------------------------------
Hi,
As previously reported - the problem was indeed resolved when running the unit
test with spring 4.0.7-RELEASE - but unfortunately when trying to run it "live"
with tomcat server I still got the same exception.
I'm attaching a zip ("Reproduce2.zip") that includes a jar that can be executed
from command-line, and contains another zip with the sources.
When running the jar it will load the camel route using spring boot.
in order to simulate the issue you need to send any POST message to
http://localhost:8080 on your machine after executing command line.
Thx,
Amit.
