&安培; NBSP;打破jsp编译 [英]   breaks jsp compilation

问题描述

我正在使用jsp开发一个带有web-GUI的项目。对于开发，我使用通过IntelliJ IDEA运行的jetty服务器。不久之前，我有一个关于JSP编译的看似随机的错误：

I'm working on a project with a web-GUI using jsp. For development I use a jetty server run through IntelliJ IDEA. A while ago I had a seemingly random error regarding JSP compilation:

apr 21, 2016 9:23:53 AM org.apache.jasper.servlet.JspServletWrapper loadTagFile
SEVERE: PWC6354: Error occurred while compiling JSP files.  
java.lang.NullPointerException

我第一次通过在IDEA中使缓存无效并重建我的项目来摆脱它。从那以后，我有一些具体的更改产生了这个错误：

The first time around I got rid of it by invalidating caches and rebuilding my project in IDEA. Since that, I have had a couple of concrete changes creating this error:

1. 将spring security从3.2.8.RELEASE升级到4.0。 3.RELEASE（！）



2. 在我的jsp中添加& nbsp; 时，如下所示：

< label> Monkey& nbsp; < / label>

现在我很困惑。我发现导致这种情况发生的原因很奇怪，堆栈跟踪包括jetty，springsecurity（filter）和jasper，以及内部java调用。我需要缩小搜索范围，但我不知道从哪里开始。有什么想法吗？

Now I'm quite stuck. I find the causes for this to happen strange, and the stacktrace includes jetty, springsecurity (filter) and jasper, as well as internal java calls. I need to narrow my search, but I don't know where to start. Any ideas?

这个错误似乎也似乎随机发生。我有团队成员因此必须重新安装IntelliJ。

This error also seems to occur seemingly at random. I've had team members that had to reinstall IntelliJ due to this.

推荐答案

尝试将此实体编号用于非破坏性空间&＃160;

Try using this entity number for non-breaking space
