Andreas Siepert created CAMEL-9558:
--------------------------------------
Summary: DefaultErrorHandler logs despite "handled true"
Key: CAMEL-9558
URL: https://issues.apache.org/jira/browse/CAMEL-9558
Project: Camel
Issue Type: Bug
Components: camel-core
Affects Versions: 2.16.2
Reporter: Andreas Siepert
The *assumption* is that handled exceptions will not be propagated any further.
In version {{2.15.5}} the test code (from the camel-jetty page) runs fine - but
since {{2.16.0}} the handled exception is propagated to the
{{DefaultErrorHandler}} which causes ERROR logs for every handled exception.
I could not find a hint in the release notes - so I think it's a bug.
{code}
public class MyTest extends CamelTestSupport {
@Test
public void test() throws Exception {
// using httpclient 4.3.5
CloseableHttpClient httpclient = HttpClients.createDefault();
HttpGet httRequest = new HttpGet("http://127.0.0.1:7890/myserver";);
HttpResponse response = httpclient.execute(httRequest);
assertThat(response.getStatusLine().getStatusCode(), is(500));
}
@Override
protected RouteBuilder createRouteBuilder() throws Exception {
return new RouteBuilder() {
@Override
public void configure() throws Exception {
from("jetty://http://localhost:7890/myserver";).tracing()
// use onException to catch all exceptions and return a
custom reply message
.onException(Exception.class).handled(true)
// create a custom failure response
.transform(constant("Dude something went wrong"))
// we must remember to set error code 500 as
handled(true)
// otherwise would let Camel thing its a OK response
(200)
.setHeader(Exchange.HTTP_RESPONSE_CODE,
constant(500)).end()
// now just force an exception immediately
.throwException(new IllegalArgumentException("I cannot
do this"));
}
};
}
}
{code}
