Как я могу найти основную причину проблемы с классом, не найденным в OSGi?

Я хочу попробовать несколько шагов, чтобы исправить проблему ClassNotFound. Я использую Equinox/OSGI. Например, я получаю

   java.lang.ClassNotFoundException: org.wso2.carbon.tomcat.ext.servlet.DelegationServlet
    at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1714)
    at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1559)
    at org.apache.catalina.core.DefaultInstanceManager.loadClass(DefaultInstanceManager.java:532)
    at org.apache.catalina.core.DefaultInstanceManager.loadClassMaybePrivileged(DefaultInstanceManager.java:514)
    at org.apache.catalina.core.DefaultInstanceManager.newInstance(DefaultInstanceManager.java:133)

Я пробовал команды ss, ls -c, diag, b... но не смог найти никакой полезной информации. Я помещаю вывод этих команд..

Может ли кто-нибудь сообщить мне, как я могу решить такие проблемы с OSgi и как я могу выяснить основную причину таких проблем.
