----------------------------------

             Summary: null body after exception from transform method
                 Key: CAMEL-8871
                 URL: https://issues.apache.org/jira/browse/CAMEL-8871
             Project: Camel
          Issue Type: Bug
          Components: camel-core
    Affects Versions: 2.15.2
            Reporter: Hans Orbaan
            Priority: Critical


When an exception is thrown from a transform method I lose the content of the message body. This behaviour is unexpected because it does not happen when an exception is thrown from a bean call.

.bean(ErrorBean.class, ErrorBean.METHOD)
Vs.
.transform().method(ErrorBean.class, ErrorBean.METHOD)

I have a testcase that I will try to get attached but here are the routes:
{code:java}
if ("testTransformExceptionToErrorRoute".equals(getTestMethodName())) {
                    from(START)
                    .routeId("exception.test.transform")
                    .transform().method(ErrorBean.class, ErrorBean.METHOD)
                    .to(END);
                } else {
                    from(START)
                    .routeId("exception.test.bean")
                    .bean(ErrorBean.class, ErrorBean.METHOD)
                    .to(END);
                }

    public static class ErrorBean {
        private static final String METHOD = "throwException";
        public static void throwException(Exchange exchange) {
            String body = exchange.getIn().getBody(String.class);
            Assertions.assertThat(body).isEqualTo(BODY);
            throw new AssertionError();
        }
    }
{code}
