NinePatchDrawable causes ClassCastException in Android Studio 0.3.6

Question

Situation:

NinePatchDrawable in custom view causing java.lang.ClassCastException in the Android Studio 0.3.6 XML Layout Editor.

The occurring error is straightforward however the reason is not. Worth noting is that the error arose and was not originally there (a few weeks ago).

java.lang.ClassCastException: android.graphics.drawable.StateListDrawable cannot be cast to android.graphics.drawable.NinePatchDrawable

Code and Resources:

This code line is causing the issue:

mTestImage = (NinePatchDrawable) mContext.getResources().getDrawable(R.drawable.img_test);

This is the error log:

java.lang.ClassCastException: android.graphics.drawable.StateListDrawable cannot be cast to android.graphics.drawable.NinePatchDrawable

This is the NinePatchDrawable:

Test Image (upscaled)

Project Structure (contains actual names however the issue and resource layout are the same)

Still can't post images until 2 more rep is acquired :(

Question:

Can anybody reproduce this? Does anybody have a similar issue?

Currently occurs in Android Studio 0.3.6 - ADT an Build Tools 19 - SDK 22.3 - Android 4.4
