public class KotlinLateinitFilter
extends CoverageFilter

Lateinit property extra branch should be ignored.

Lateinit property access generates such sequence of code inside class: in Kotlin version less or equal than 1.4

1. GETFIELD
2. IFNONNULL
3. LCD name
4. INVOKESTATIC kotlin/jvm/internal/Intrinsics.throwUninitializedPropertyAccessException (Ljava/lang/String;)V

or in Kotlin version greater than 1.4

1. GETFIELD
2. IFNULL
3. LCD name
4. INVOKESTATIC kotlin/jvm/internal/Intrinsics.throwUninitializedPropertyAccessException (Ljava/lang/String;)V

For internal classes direct access to a field of the containing class is replaced with access to the containing class (GETFIELD) and then a call to an access method.
