Reified T - Invalid Code Coverage

[gibarrola-mdt]

Kover 0.8.1 and previous versions are incorrectly calculating the branch % for some reified extensions. Below is a snippet on how to reproduce the observed error:

Internal Function:

internal inline fun <reified T> sizeOf() : Int where T : Number =
    when(T::class)
    {
       Byte::class -> Byte.SIZE_BYTES
       Short::class -> Short.SIZE_BYTES
       Int::class -> Int.SIZE_BYTES
       Long::class -> Long.SIZE_BYTES
       Float::class -> Float.SIZE_BYTES
       Double::class -> Double.SIZE_BYTES
       else -> throw Exception("Unsupported type")
    }

Unit Test - results in partial "Branch, %" coverage although the "Instruction, %" is 100%:

@Test
fun sizeOfTest() {
    assertEquals(1, sizeOf<Byte>())
    assertEquals(2, sizeOf<Short>())
    assertEquals(4, sizeOf<Int>())
    assertEquals(8, sizeOf<Long>())
    assertEquals(4, sizeOf<Float>())
    assertEquals(8, sizeOf<Double>())
    
    assertFailsWith<Exception> {
       sizeOf<InvalidNumberClass>()
    }
}

private class InvalidNumberClass(private val number: Number): Number() {
    override fun toByte() = number.toByte()
    override fun toShort() = number.toShort()
    override fun toInt() = number.toInt()
    override fun toLong() = number.toLong()
    override fun toFloat() = number.toFloat()
    override fun toDouble(): Double = number.toDouble()
}
