tomcat 上的 liferay 不加载类
我正在 Liferay 上制作一个部署在 jboss 上的 portlet。今天我换了一个库，开始出现问题。当我部署一个portlet时，我必须重新启动Liferay，否则我会遇到这个异常：
17:09:36,325 ERROR [DispatcherPortlet:554] Could not complete request
java.lang.NullPointerException

今天早上，当我尝试使用log4j的记录器时，我遇到了类似的问题...现在这个问题与公共日志有关...有人可以帮忙我？

我认为您在 Tomcat 中遇到了错误。因为它不应该抛出 RuntimeException 尤其是 NullPointerException。怎么处理呢？阅读tomcat的源代码第1245行...
i think you met a bug in Tomcat. because it should not throw a RuntimeException especially NullPointerException. how to deal with it? read the source code of tomcat at line 1245...
