Vadim Chekan commented on CAMEL-927:
------------------------------------
I upgraded to the current trunk and I still see exception every time I run it.
Claus, there is a bug in the unit test: in my 2nd example two routes are
concatenated by dot, not by semicolon. In other words it is a single java
statement. Could you check it please? If you still can not reproduce it then
I'll keep digging.
Yes, when there is any output then double input works fine. I'm playing with my
DSL and I'm testing weird combinations :)
