我们有NPE在coe的行中提到的主题时呼吁

RoutesDefinition routesDefinition=context.loadRoutesDefinition(new ByteArrayInputStream(value.getBytes(StandardCharsets.UTF_8)));

在Apache Camel中。也就是从XML配置加载路由时。很明显，导致异常的问题是XML中的一些不明确的更改，仍然使其有效，但不知何故使其失败。我认为，在验证XML的一致性时，应该早些抛出错误消息。现在，它是一种运行时异常。

路线的关键部分是：

<when>
                        <log message="Processing as sattelites are more than 0"/>
                        <setHeader headerName="timestamp">
                            <jsonpath>$.t</jsonpath>
                        </setHeader>
                        <setHeader headerName="messageId">
                            <simple>${header.unit_id}-${header.timestamp}</simple>
                        </setHeader>
                        <setHeader headerName="kafka.KEY">
                            <simple resultType="java.lang.String">${header.unit_id}</simple>
                        </setHeader>
                        <idempotentConsumer messageIdRepositoryRef="deduplicationRepo">
                            <header>messageId</header>
                            <removeHeaders pattern="*" excludePattern="messageId|kafka\.KEY"/>
                            <to uri="micrometer:timer:camel.proxy.minifinder.getmessages.kafka?action=start" />
                            <log message="Deduplicated: body\n ${body}"/>
                            <to uri="micrometer:timer:camel.proxy.minifinder.getmessages.kafka?action=stop" />
                        </idempotentConsumer>
                    </when>

但我认为不应该退出任何配置来引发此异常。
