情况：
自定义视图中的NinePatchDrawable导致Android Studio 0.3.6 XML布局编辑器中的java.lang.ClassCastException。
发生的错误很简单，但原因并非如此。值得注意的是，错误出现了并且最初并不存在（几周前）。
java.lang.ClassCastException: android.graphics.drawable.StateListDrawable cannot be cast to android.graphics.drawable.NinePatchDrawable
代码和资源：
此代码行导致问题：
mTestImage = (NinePatchDrawable) mContext.getResources().getDrawable(R.drawable.img_test);
这是错误日志：

这是NinePatchDrawable：
Test Image（升级）
Project Structure（包含实际名称，但问题和资源布局相同）
在获得2个以上的代表之前仍然无法发布图像:(
问题：
有人可以复制这个吗？有没有人有类似的问题？
目前发生在Android Studio 0.3.6 - ADT构建工具19 - SDK 22.3 - Android 4.4
