Oh, I forgot again to change in build.gradle the repositories. So indeed with old code I see too the exception on 5.1.1, good finding! 🙂

Can be easily fixed as there is also a free method: https://android.googlesource.com/platform/libcore/+/android-5.0.2_r1/luni/src/main/java/java/nio/DirectByteBuffer.java
