从Servicemix 7.0.0M2升级到6.1.0时，我从我的某个捆绑包中获得以下异常。

相同的pom.xml在6.1.0上工作正常，只是在转移到7.0.0M2时我将camel.version更改为2.16.3并2.16.1来自jackson.version的{{1}}和jackson.afterburner.version至2.7.5。
有人能让我知道出了什么问题吗？从2.6.2搬到7.0.0M2时，我是否需要更改其他内容？

修改我的pom.xml和feature.xml以使用camel-jetty9解决了这个问题。
我在pom.xml
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-jetty9</artifactId>
<version>${camel.version}</version>
<scope>provided</scope>
</dependency>
以下feature.xml的变化： -
<feature version="${camel.version}">camel-jetty9</feature>
其中<camel.version>2.16.3</camel.version>

是的骆驼版 2.16.3 我也不得不卸载camel-jetty。只有 camel-jetty9 似乎有效。
feature:uninstall camel-jetty/2.16.3
