Background

We have the following code:

enum class AnimationType(val interpolator: TimeInterpolator) {
    LINEAR(LinearInterpolator()),
    EASE_IN(AccelerateInterpolator()),
    EASE_OUT(DecelerateInterpolator()),
    EASE_IN_OUT(AccelerateDecelerateInterpolator());

    companion object {
        val ANIMATION_LOOKUP = mapOf(*AnimationType.values().map { Pair(it.ordinal, it) }.toTypedArray())
    }
}

This is getting compiled into:

public enum IL {
    LINEAR(new LinearInterpolator()),
    EASE_IN(new AccelerateInterpolator()),
    EASE_OUT(new DecelerateInterpolator()),
    EASE_IN_OUT(new AccelerateDecelerateInterpolator());

    public final TimeInterpolator a;
   
    ...

    // TimeInterpolator changed to BaseInterpolator!!
    IL(BaseInterpolator baseInterpolator) {
        this.a = baseInterpolator;
    }
}

Note, the constructor for the enum is now BaseInterpolator instead of TimeInterpolator. BaseInterpolator was introduced in SDK 22 (5.1) so this now crashes on Android 5.0 with NoClassDefFound.

The prior compiledumps sent should reproduce this issue. If you don't have that anymore, I can send a new one.
