我们有一个Web应用程序(war),它在使用默认配置的情况下成功部署到JBoss EAP 7.3域模式下,但是在单机模式下(基于默认standalone.xml配置)部署失败,并出现以下错误:

在这两种情况下,战争和应用程序配置是相同的。
JBoss配置在两种情况下尽可能接近。在域模式下,它基于默认配置文件配置,并仅添加了一些资源。在独立模式下,它基于默认的standalone.xml配置文件,并添加了相同的一组资源。因此,从这个角度来看,我找不到导致行为差异的任何原因。
到目前为止,我们已经跟踪到 tomcat-embed-el-9.0.39.jar 这个JAR包由于某些第三方依赖而包含在我们的WAR包中。这个JAR包包含一个名为META-INF/services/javax.el.ExpressionFactory
的文件,其中包含以下内容:

问题显然是第一行被读取并处理为实际条目(例如类名),尽管它只是一条注释。 因此,这类似于影响 EAP 6 的以下旧问题: https://access.redhat.com/solutions/1270603(需要 Red Hat 登录)。
但奇怪的是,这仅在独立模式下发生。 这可以被视为一个错误吗?
注意:我们在 JBoss EAP 7.3.0 和 7.3.6 上进行了测试,结果相同。
