camel-mina if exchange failed then out could potentially be a copy of in
------------------------------------------------------------------------
Key: CAMEL-364
URL: https://issues.apache.org/activemq/browse/CAMEL-364
Project: Apache Camel
Issue Type: Bug
Components: camel-mina
Affects Versions: 1.3.0
Reporter: Claus Ibsen
Priority: Minor
Using the camel-mina component in synchronous mode (InOut exchange pattern)
there is a potential bug if eg a processor throws an exception.
This is a failed delivery in camel. And out-of-the-box the default policy is to
retry up till 6 times. And if still failing camel-mina will continue and return
a response to the client.
The respons is a duplicate of the in body.
A workaround is to set the out body to null immediately in your processor. If
the body is null before the exception is thrown then camel-mina will no return
a response.
To reproduce the bug see the MinaTcpWithInOutUsingPlainSocketTest and remove
the setbody null code below and the test should fail.
{code}
else if ("force-exception".equals(in)) {
// clear out before throwing exception
e.getOut().setBody(null);
throw new IllegalArgumentException("Forced
exception");
}
{code}
In MinaConsumer there is a TODO comment where the bug should be handled (from
CAMEL-356)
