Camel HTTPS4调用失败，但CamelHttpResponseCode标头显示200

Question

我正在使用通过https4组件（camel版本2.14.0）通过HTTP请求资源的路由。死信通过将失败的交换路由到日志端点来处理错误，如下所示：

MATCH (t:Topic)
WHERE id(t) = 4
RETURN size((t)<-[:DOWNVOTED]-(:Person)) as downvoted,
       size((t)<-[:UPVOTED]-(:Person)) as upvoted,
       size((t)<-[:FLAGGED]-(:Person)) as flagged

如果网关超时（504），则会引发.to("log:backendFailed?level=WARN&showAll=true") ，表示错误，并按预期记录交换。由于我设置了HttpOperationFailedException，因此会记录交换的所有标头，包括showAll=true。日志看起来像这样：

CamelHttpResponseCode

CamelFailureEndpoint=https4://backend?httpClient.socketTimeout=70000&httpClient.connectTimeout=70000, ... CamelToEndpoint=log://backendFailed?level=WARN&showAll=true ... CamelHttpResponseCode=200, CamelHttpUri=https://example.com/myresource, ... CaughtExceptionType: org.apache.camel.component.http4.HttpOperationFailedException, CaughtExceptionMessage: HTTP operation failed invoking https://example.com/myresource with statusCode: 504, StackTrace: org.apache.camel.component.http4.HttpOperationFailedException: HTTP operation failed invoking https://example.com/myresource with statusCode: 504 标题不应该在这里说504？
