将 sun 应用程序服务器 8.2 升级到新的补丁级别时发生异常,我不知道为什么。遵循来自Servlet的代码片段:
public void init() throws ServletException {
Properties reqProperties = new Properties();
try {
reqProperties.load(this.getClass().getResourceAsStream(
"/someFile.properties"));
} catch (IOException e) {
e.printStackTrace();
}
...
}
该文件确实存在于类路径中,并且在以前的补丁版本中它工作得很好。但是现在在部署此结果时会出现异常。堆栈跟踪:

我不知道任何人有什么想法可能是什么问题?(请注意,我在代码和堆栈跟踪中更改了一些名称)
