----------------------------------------
Summary: camel-netty-http and camel-undertow: align muteException
default with the other HTTP components
Key: CAMEL-23651
URL: https://issues.apache.org/jira/browse/CAMEL-23651
Project: Camel
Issue Type: Improvement
Components: camel-netty-http, camel-undertow
Reporter: Andrea Cosentino
Assignee: Andrea Cosentino
Fix For: 4.21.0, 4.18.3, 4.14.8
h4. Background
The muteException consumer option is inconsistent across the HTTP server
components:
* camel-http, camel-jetty and camel-servlet (via HttpCommonComponent) default
muteException to true.
* camel-platform-http defaults muteException to true.
* camel-netty-http and camel-undertow default muteException to false.
With muteException=false a consumer-side processing failure returns the
exception stack trace in the response body as text/plain; with
muteException=true the response body is empty. The two groups behave
differently out of the box.
h4. Proposal
Align camel-netty-http and camel-undertow with the other HTTP server components
by defaulting muteException to true.
* camel-netty-http: initialise the field in NettyHttpConfiguration to true, set
the same default in NettyHttpComponent, add defaultValue = "true" to the
@UriParam, and regenerate the catalog metadata.
* camel-undertow: set the default in UndertowComponent to true, add
defaultValue = "true" to the @UriParam, and regenerate the catalog metadata.
h4. Compatibility
This changes the default behaviour. Users who rely on the exception stack trace
being present in the response body must set muteException=false explicitly
after the upgrade. The change must ship with an upgrade-guide note on each
affected release line.
h4. Backport
Backport to 4.18.x and 4.14.x. The option and its current false default are
present on both branches.
