Tomcat环境Jackson版本冲突致RuntimeException及Shading依赖问题求助

背景 #

我开发的Java插件运行在厂商基于Tomcat的应用服务器上，厂商代码不可修改，仅能通过其框架扩展接口实现自定义功能。厂商将Java版本从11升级至17后，插件出现功能回归问题。

我们已确保Maven pom.xml指定Java 17为目标版本，且所有fasterxml.jackson依赖版本统一为2.13.2：

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-core</artifactId>
    <version>2.13.2</version>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-annotations</artifactId>
    <version>2.13.2</version>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.13.2</version>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.module</groupId>
    <artifactId>jackson-module-jaxb-annotations</artifactId>
    <version>2.13.2</version>
</dependency>

问题排查与报错信息 #

排查发现厂商Tomcat的lib目录存在2.9.8版本的Jackson旧库，该版本无TokenStreamFactory类，但无法修改厂商代码。当前报错信息如下：

尝试方案与待解决问题 #

推测是旧版本Jackson干扰所致，尝试通过Shading将Jackson 2.13.2打包至common.jar，并将包路径重命名为my.shaded.com.fasterxml.jackson。但依赖该包的XYZ插件无法引用重命名后的类（如my.shaded.com.fasterxml.jackson.annotation.JsonIgnoreProperties），寻求解决该依赖引用问题的方法。
