Java 启动时RAD工作区错误/RAD许可证冲突

我启动了RAD，我的工作区充满了错误

☞ 我试图在工作区中打开的每个现有

.java

文件都会出现此错误

---

☞ 我在现有的

.xsl

文件中遇到此错误

无法打开编辑器：无法实例化编辑器类。这通常表示缺少无参数构造函数，或者编辑器的类名在plugin.xml中输入错误。

☞ 当我尝试启动

WebSphereApplicationServer8.5

时出现此错误

---

☞ 我在尝试打开现有的

.jsp

文件时遇到此错误

无法打开编辑器：无法实例化编辑器类。这通常表示缺少无参数构造函数，或者编辑器的类名在plugin.xml中输入错误。

我做了一个工作区

clean

，并用

-clean

重新启动了RAD，但仍然出现错误！关于如何解决这个问题有什么建议吗？

各位，问题似乎出在RAD的

许可证配置上。最近，我的工作站上的许可证从
浮动
切换为
永久
许可证，然后桌面团队重新分配了永久安装并删除了浮动安装分配。发生这种情况时，
安装管理器对使用哪个许可证感到困惑。当浮动许可证被禁用时，它获取了永久许可证并使我摆脱了所有错误。感谢我们的系统工程师


希望这对别人有帮助
 以前有用吗？在它停止工作之前，你做了什么？@ChrisGerken我早些时候纠正了这个错误：然后我做了一次清洁，昨天它工作得很好。我当时关闭了工作区，今天打开却发现了这些错误。
