Tracer Interceptor - Problem - modify the body of a message

[dherla]

Hello,

I use : apache-servicemix-4.3.1-fuse-01-09

I deploy via blueprint.xml

I have a very simple route like this :

from("file:c:/p06293/camel/test-in/")

  .process(new Processor() {

    public void process(Exchange exchange) throws Exception {

       File body = exchange.getIn().getBody(File.class);

       log.debug("The body is {}",body);

    }

  })

.to("file:c:/p06293/camel/test-out");

If the Trace is false at the camelcontext, i received the following log :

The body is c:\p06293\camel\test-in\test-1.zip

If the Tracer is true at the camelcontext, i received the following log :

The body is null

I don't understand why there is a change when i set the tracing.

Thanks in advance

Dimitri

The tracer outputs the message body and thus it loads the File into memory and the message body becomes a input stream instead.

I think we have changed the tracer in Camel 2.8 onwards to not load content of stream/files. So in a future ESB release that should be fixed for you.
