----------------------------------------
Summary: camel-mina - add a muteException consumer option
Key: CAMEL-24476
URL: https://issues.apache.org/jira/browse/CAMEL-24476
Project: Camel
Issue Type: Improvement
Components: camel-mina
Reporter: Andrea Cosentino
Assignee: Andrea Cosentino
Fix For: 4.23.0
CAMEL-23651 aligned the {{muteException}} consumer option so that a failed
exchange does not return the exception's stack trace or message to the remote
caller. The option exists in camel-http-common (and therefore camel-servlet and
camel-jetty), camel-http, camel-netty-http, camel-platform-http and
camel-undertow. A grep for {{muteException}} across {{components/}} still shows
it in the http family only.
Split out of CAMEL-24428 so that each component can be tracked, fixed and
released on its own.
{{MinaConsumer}} writes the route's exception straight back over the socket
when the exchange failed and {{transferExchange}} is off:
{code:java}
boolean failed = exchange.isFailed();
if (failed && !getEndpoint().getConfiguration().isTransferExchange()) {
if (exchange.getException() != null) {
response = exchange.getException();
}
...
}
if (response != null) {
MinaHelper.writeBody(session, response, exchange,
configuration.getWriteTimeout());
}
{code}
The remote peer therefore receives the {{Throwable}} - its message, and with
the object codec its serialised form, including the cause chain.
Proposal: add a {{muteException}} consumer option, defaulting to {{true}} to
match the post-CAMEL-23651 behaviour of the http family, with an upgrade-guide
entry noting that routes relying on the detail must set it to {{false}}
explicitly.
