无法在 Camel 3.8.0 中配置 doCatch 块 XML

Question

从 Camel 3.8.0 开始，我无法在 XML 中配置 doCatch 块，如下所示：

<routes xmlns="http://camel.apache.org/schema/spring"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://camel.apache.org/schema/spring https://camel.apache.org/schema/spring/camel-spring.xsd">

    <route>
        <from uri="direct:start"  />
        <doTry>
            <to uri="log:try" />
            <doCatch>
                <exception>java.lang.RuntimeException</exception>
                <to uri="log:catch" />
            </doCatch>
        </doTry>
    </route>
</routes>

我得到

Caused by: java.lang.IllegalArgumentException: This doCatch should have a doTry as its parent on DoCatch[ [class java.lang.RuntimeException] -> [To[log:catch]]]

    ... 26 common frames omitted

据我了解，这意味着 doCatch 块缺少其父块 (doTry)。我调试的时候，parent确实是null。

我是不是遗漏了什么，或者这是一个错误或更改 API？非常感谢！

此版本的 Apache Camel (https://issues.apache.org/jira/browse/CAMEL-16534) 中存在错误，已在 3.10.0 中修复。
