Mock fail when use dexmaker-mockito-inline instead of dexmaker-mockito

Nobody has claimed this yet.

I can mock "com.android.bluetooth.btservice.AdapterService" when i include "dexmaker-mockito"

But I want to mock final class (android.bluetooth.BluetoothDevice),
so i changed "dexmaker-mockito" to "dexmaker-mockito-inline".

Then runtime error is occurred like below.

AdapterService class code is below.

package com.android.bluetooth.btservice;

public class AdapterService extends Service {
...

static {
classInitNative();
}

...

static native void classInitNative();

...
}

I can't understand why "dexmaker-mockito" has no problem, but "dexmaker-mockito-inline" has upper problem.
There is some difference about mocking native method?

Thank you.

Start with the failing call at com.android.bluetooth.hfp.HeadsetAudioManagerTest.java:44 and trace InlineDexmakerMockMaker.createMock through MockMakerMultiplexer. Compare the inline path with the regular dexmaker-mockito path, focusing on AdapterService's static classInitNative() initializer. Done means the reported final-class mock no longer fails with UnsatisfiedLinkError, or the incompatibility is clearly documented.
