Spring Error on Plugin Enable when including `org.jetbrains.teamcity.internal server` dependency

I am writing a plugin that uses the SBuildPromotionEx interface provided by the `org.jetbrains.teamcity.internal server` dependency to add custom parameters before build start.  Prior to adding this dependency, my plugin worked fine. After including it and uploading the new zip, I get the below error text.  

org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from URL [jar:file:/opt/teamcity/webapps/ROOT/WEB-INF/lib/common-impl.jar!/META-INF/per-plugin-shared-spring.xml]; nested exception is org.springframework.beans.FatalBeanException: Class [org.springframework.context.config.ContextNamespaceHandler] for namespace [http://www.springframework.org/schema/context] does not implement the [org.springframework.beans.factory.xml.NamespaceHandler] interface

Here is my plugin xml:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"
       default-autowire="constructor">
    <bean class="package.class1" />
    <bean class="package.class2"/>
    <bean class="package.class3"/>
</beans>

and the dependencies from my pom.xml

I tried this on both Teamcity 2024 and 2025, and the results were the same. I also verified that I'm using the same version of spring in the plugin as my Teamcity instance. I know the SBuildPromotionEx interface can be used in plugins--we have another similar plugin that I can load just fine. I can't tell what about my plugin configuration might be causing issues when including this dependency.
