我一直在尝试获得使用 openEJB 对项目进行单元测试的设置。我从现有项目中复制了大部分配置，该项目使用 hibernate-entitymanager 版本 3.3.2.GA ，但新项目使用版本 3.4.0.GA。当我指定实体管理器的 3.3.2.GA 版本时，我的单元测试有效，但在使用 3.4.0.GA 时无效

这是我与单元测试有关的 pom 设置：

        <dependency>
        <groupId>org.apache.openejb</groupId>
        <artifactId>javaee-api</artifactId>
        <version>5.0-2</version>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>org.apache.openejb</groupId>
        <artifactId>openejb-server</artifactId>
        <version>3.1.1</version>
        <scope>test</scope>
        <exclusions>
            <exclusion>
                <artifactId>org.apache.openjpa</artifactId>
                <groupId>openjpa</groupId>
            </exclusion>
        </exclusions>
    </dependency>
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-c3p0</artifactId>
        <version>3.3.2.GA</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-entitymanager</artifactId>
        <version>3.4.0.GA</version>
    </dependency>
</dependencies>

我试图提高 openejb 服务器的版本号，但我的堆栈跟踪中不断出现以下异常：

这看起来像是 Hibernate 和 openEJB 之间的依赖问题，我只是不确定要使用哪个版本的 openejb。

这是查询：

"SELECT u FROM User u WHERE u.name = :name"
