Osgi 获取MultiTenataDressingBasedDispatcher的java.lang.ClassNotFoundException

我正在从wso2 app server 5.1.0获取其中一个JAR的类not found异常。 我在这里复制了堆栈跟踪，如下所示：

经过一番搜索，我发现org.wso2.carbon.core_4.1.0包含该类 org.wso2.carbon.core.multi-tenance.multi-tenantadDressingBasedDispatcher。 我仍然不清楚这个类对classloader的可见性，即使它的包是活动的

关于这方面的任何指导方针都将非常有用。。

感谢和问候，Parimal

httpcore nio版本似乎有问题，所提到的版本更改不在包中
