>关闭并尝试重新打开文件会生成一个空白选项卡.
>尝试打开其他文件也会生成空白选项卡.
>打开多个选项卡会生成NullPointerException.
>重新启动Eclipse会将Eclipse恢复到功能状态.
>使用JS编辑器(Chrome图标)代替JavaScript编辑器似乎可以解决问题(只有在尚未触发上述错误时才有效).

>我担心使用JS编辑器会阻止我使用依赖JavaScript编辑器工作的其他插件.

我尝试了什么

>卸载未签名的插件(AngularJS Eclipse)
>重新安装Eclipse Neon
>重新安装未签名的插件(AngularJS Eclipse – 与上面相同)

笔记

为了首先启动Eclipse Neon,从eclipse.ini中删除了以下行：

-vmargs

临时解决方案

如howlger’s answer所示,这是由JavaScript编辑器未正确处理解析异常引起的问题.

这是原始文件的精简版本,证明了问题：

(function() {
    var app = angular.module('TestModule', []);

    app.controller("TestController", [ '$http', function($http){

    ]});
})();

> online Esprima parser让我发现我在第6行放错了方括号.

这是修复后的代码：

(function() {
    var app = angular.module('TestModule', []);

    app.controller("Test Controller", [ '$http', function($http) {

    } ]);
})();

解决方法:

Eclipse Neon包含JavaScript开发工具(JSDT)2.0,它使用Esprima作为解析器. (Esprima是用JavaScript编写的,由JSDT通过Nashorn执行.)在您的情况下,Esprima无法解析您的JavaScript文件,并且JSDT 2.0不是非常强大(没有回退策略)来处理这类问题.尝试parse your file with Esprima online. JSDT知道这些Esprima问题和plan to replace it in an upcoming version(Eclipse bug 497249),可能在9月的Neon.1.不幸的是,只要JSDT无法解析您的文件,您就无法使用JSDT JavaScript编辑器.
