这刚刚开始发生在我身上，但是每次我尝试访问“服务器”视图（“窗口”>“显示视图”>“服务器”）时，图标或窗口都会短暂出现，然后消失。
当窗口短暂闪烁时，我能够捕获到消息：
No Servers Available. Please click link to create a Server
这很奇怪，因为我在（Windows>首选项>服务器>运行时环境）中创建了服务器。我还能够从下面包含的日志文件中找到一个BasicIndexOutOfBoundsException。
我认为可能造成此问题的唯一原因是，我已将Dynamic Web Project部署到服务器，然后删除了该Web项目。我不记得服务器是在启动还是停止的。
有人知道发生了什么吗？如何解决此问题（在重新安装卸载之外）？是否可以添加Web项目并启动服务器？
