Seeing different behaviour in Jacoco coverage while using sealed class on kotlin 1.6.20

[arpank10]

Steps to reproduce

• JaCoCo version: 0.8.8
• Operating system: MacOS
• Tool integration: Gradle/Kotlin
• Complete executable reproducer:
  Attached as a zip
  jacocoReproducer.zip

Steps: (what exactly are you doing with the above reproducer?)

To generate the test reports execute
./gradlew kotlinjacocoTestReport
in the above reproducer.

Same can be run after changing the kotlin version in build.gradle file's plugin section
id 'org.jetbrains.kotlin.jvm' version '1.6.20'

Expected behaviour

For both kotlin 1.4.32 and 1.6.20 coverage should be same for sealed classes

Actual behaviour

For file PreviewScaleType.kt in the attached zip

Using sealed classes with parameterized constructor produces 3 methods for 1.4.32

For the same piece of code with kotlin 1.6.20 it produces 2 methods

@arpank10 your jacocoReproducer.zip doesn't seem to correspond to your screenshots:
after downloading and unpacking, execution of the command

./gradlew kotlinjacocoTestReport

produces the following report

notice that there are classes PreviewScaleType.Companion, PreviewScaleType.FitY and PreviewScaleType.FitX, but no PreviewScaleType that is shown on your screenshots.

And this report is actually the same as the one already packaged in provided jacocoReproducer.zip

[arpank10]

My bad, we were experimenting with different constructors, and removed the parameterised one.
Here is the working reproducer with both kotlin versions:
jacocoReproducer_1.4.32.zip
jacocoReproducer_1.6.20.zip

@Godin Any updates on this?

@arpank10 No need to ask. Any update would be posted here.
