Test Parcel with Serializable with Robolectric 2

Issue

I want to test if my Class write the right data in the Parcel, so i wrote following test.:

@Test
public void parcelOutAndIn() {
    Trip trip = new Trip("id123", new Date());

    Parcel parcel = Parcel.obtain();
    trip.writeToParcel(parcel, 0);
    Trip tripResult = new Trip(parcel);

    Assert.assertThat(tripResult.getId(), equalTo(trip.getId()));
    Assert.assertThat(tripResult.getStartTime(), equalTo(trip.getStartTime()));
}

my writeToParcel looks like this:

@Override
public void writeToParcel(Parcel parcel, int i) {
    parcel.writeString(id);
    parcel.writeSerializable(startTime);
}

I've got following Error:

java.lang.NoSuchMethodError: java.util.Arrays.checkOffsetAndCount

What can i do? Is it a Bug in Robolectric? I use Robolectric 2.1.1.

The Stacktrace:

Solution

Unfortunately, Roboelectric's ShadowParcel doesn't include implementation for the writeByteArray() method.
