我在安装了最新 Java 的 Mac 上。我安装了 Eclipse 4.2.0 并且刚刚下载了 Jelly Bean 4.1 (API 16) SDK。一切都是最新的。
我开始一个新项目并使用所有默认模板和值。我只是将我的应用称为“MyApp”之类的简单应用。
当我将按钮从工具箱拖到所见即所得编辑器时，按钮显示正常，我可以编辑 XML，一切都很好，等等。
但是当我拖动纯文本框时，我收到以下 Java 错误，并且我的整个 WYSIWYG 编辑器变为灰色。唯一能让它恢复原状的方法是从 XML 中删除代码并重新启动 Eclipse。如果我将代码粘贴回去，错误就会回来。
这是错误：
java.util.LinkedHashMap.eldest()Ljava/util/Map$Entry;
Exception details are logged in Window > Show View > Error Log
这是导致它的代码：
<EditText
android:id="@+id/editText1"
android:inputType="text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignTop="@+id/button1"
android:layout_marginLeft="55dp"
android:ems="10"
android:hint="@string/hello_world" >
<requestFocus />
</EditText>
我知道今天果冻豆是全新的，但有人对这里可能发生的事情有任何想法吗？
其他人可以重现这个问题吗？
顺便说一句，我不会因为其他文本字段类型（如密码、人名等）而崩溃。只有纯文本。

这是来自 Eclipse 的堆栈跟踪：
