Apfloat Pi is returning null

I'm using the Apfloat library of version 1.8.3 During my computation i need to calculate value of pi with appropriate precision. At the moment i'm using ApfloatMath.pi method and the code looks like this

object Problem461 extends App {
  val Pi = ApfloatMath.pi(200)

During unit test i'm receiving NullPointerException since ApfloatMath.pi is returning null. I have tried many things, set different precisions, including Apcomplex.DEFAULT, and tried to create apfloat.properties resource bundle but result of ApfloatMath.pi is still null.

How i supposed to use this method?

UPDATE

I have just solved this issue by declaring Pi as lazy val :

 lazy val Pi = ApfloatMath.pi(100)

Also i've made sure Pi is calculated correctly as simple val during just plain run, not unit test.

So main question changes to:

What could be uninitialized in the apfloat lib during val calculaction at the moment of unit test?
