在启用类跟踪时，发现websphere正在从同一个guava-30.0-jre.jar加载同一包（com.google.common.util.concurrent）中的其他类
com.google.common.util.concurrent包中的类总数：310，加载的类总数：285（根据类加载跟踪）
尝试的解决方案：
类加载顺序设置为父级最后一个
在applicationservers>server1>processdefinition>javavirtualmachine下的genericjvm参数中显式设置jar路径
还尝试创建一个共享库，并通过部署的web应用引用它。创建共享库所遵循的步骤来自此url
jar文件也可以，反编译没有任何问题
机器重新启动
下面是一个堆栈跟踪以供参考：

请注意，当在weblogic、tomcat和jboss中部署相同的web应用程序时，一切正常
