AnimatedVectorDrawable in Support Library and animation of "pathData"

I am using animated vectors from Support Library 23.2.0, like this:

compile 'com.android.support:support-vector-drawable:23.2.0'
compile 'com.android.support:animated-vector-drawable:23.2.0'

I am trying to animate "pathData" (morphing lines one to another). My code looks like this.

drawable/ic_done.xml:

<?xml version="1.0" encoding="utf-8"?>
<vector xmlns:android="http://schemas.android.com/apk/res/android"
    android:width="24dp"
    android:height="24dp"
    android:viewportHeight="24.0"
    android:viewportWidth="24.0">
    <path
        android:name="tick"
        android:pathData="M4.8,12L9,16.2L20,8"
        android:strokeColor="#FF000000" />
</vector>

drawable/ic_done_animated.xml:

<?xml version="1.0" encoding="utf-8"?>
<animated-vector xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:drawable="@drawable/ic_done">
    <target
        android:name="tick"
        android:animation="@animator/tick_path_animation" />
</animated-vector>

animator/tick_path_animation.xml:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:ordering="sequentially">
    <objectAnimator
        android:duration="200"
        android:propertyName="pathData"
        android:valueFrom="M4.8,12L4.8,12L4.8,12"
        android:valueTo="M4.8,12L9,16.2L9,16.2"
        android:valueType="pathType" />
    <objectAnimator
        android:duration="200"
        android:propertyName="pathData"
        android:valueFrom="M4.8,12L9,16.2L9,16.2"
        android:valueTo="M4.8,12L9,16.2L20,8"
        android:valueType="pathType" />
</set>

Java code:

ImageView vImgAnimated = findByViewId(R.id.img);
AnimatedVectorDrawableCompat animatedVector = AnimatedVectorDrawableCompat.create(getContext(), R.drawable.ic_done_animated);
vImgAnimated.setImageDrawable(animatedVector);
animatedVector.start();

It works well on newer device with API level 21 but I have a problem on device with API level 16:

java.lang.NumberFormatException: Invalid int: "M4.8,12L4.8,12L4.8,12"

According to an article android-support-library-232 the animated vectors (AnimatedVectorDrawableCompat) should be supported back to API level 11.

It looks like it fails while reading valueFrom attribute from tick_path_animation.xml. This attribute type "pathType" is probably not supported (yet?). Any idea how to solve this?
