Double input without output produce exception
---------------------------------------------
Key: CAMEL-927
URL: https://issues.apache.org/activemq/browse/CAMEL-927
Project: Apache Camel
Issue Type: Bug
Components: camel-core
Affects Versions: 1.5.0
Reporter: Vadim Chekan
Priority: Minor
Turn trace on.
Run this route:
from("timer://kickoff_1?period=10000&delay=1");
As expected there is output from Trace Interceptor every 10 sec.
Now run this route:
from("timer://kickoff_1?period=10000&delay=1").
from("timer://kickoff_2?period=10000&delay=2");
You will get exception:

Why single input works fine and two produce an exception?
