Subject Re: Inflight and pending exchange in a route during shutdown
Date Mon, 06 Jun 2011 09:46:20 GMT
Hello,

I just switch back to Camel 2.6.0 and it works fine : no inflight pending
exchange in the file validation route.
BTW : the problem exists with the lastest release of Camel (2.7.2).

Any idea of what I should look at in detail in the Validation component ?

Thank you in advance
Best regards,
Xavier
