在启用 CDI（beans.xml）之前，我在 log4j2 的依赖项（LMAX Disruptor）上没有任何 UnsupportedClassVersionError。UnsupportedClassVersionError 告诉在 java9 而不是 java8 上运行，但这不是可选的。请告知如何在 java8 上避免此错误。

Weblogic 12.2 log4j 2.11.2

排除 log4j2 CDI 扫描如下：

豆类.xml

<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee 
                           http://xmlns.jcp.org/xml/ns/javaee/beans_1_1.xsd"
    version="1.1" bean-discovery-mode="all">
    <scan>
        <!-- Prevent java.lang.NoClassDefFoundError: com/lmax/disruptor -->
        <exclude name="org.apache.logging.**" />
    </scan>
</beans>
