Steve Huston commented on CAMEL-2762:
-------------------------------------
I notice that this problem exists in Camel 2.19.1.
I can try it on 2.22 sometime soon, but if you already know it didn't change
between 2.19 and 2.22 that wold be helpful.
> Default Tracer configuration eats Mina ByteBuffer responses
> -----------------------------------------------------------
>
> Key: CAMEL-2762
> URL: https://issues.apache.org/jira/browse/CAMEL-2762
> Project: Camel
> Issue Type: Bug
> Components: camel-mina
> Affects Versions: 2.2.0
> Reporter: Cott Lang
> Assignee: Claus Ibsen
> Priority: Major
> Fix For: 2.4.0
>
>
> It appears that the only way to get UDP responses out of Camel Mina without
> binary ( > 7 bit) getting garbled by internal conversions is to reply with a
> Mina ByteBuffer.
> Unfortunately, if you have Trace on, the DefaultTraceFormatter ends up
> calling MinaConverter.toByteArray, which "consumes" the ByteBuffer, setting
> it to empty, which means no reply goes out. :)
> {code}
> 27/05/10 07:02:41:DEBUG:org.apache.camel.component.mina.MinaConsumer:Writing
> body: DirectBuffer[pos=11 lim=11 cap=16: empty]
> {code}
> I'm not sure how to fix this one cleanly, so I don't have a patch. I might
> also be doing something wrong, if so I'm all ears. :)
