Different namespaces of CancellationException point to the same thing in JVM

Code

package com.glassthought.sandbox

import com.glassthought.sandbox.util.out.impl.out
import kotlinx.coroutines.*
import java.lang.Exception
import kotlin.time.Duration.Companion.milliseconds

fun main(): kotlin.Unit = runBlocking {

  supervisorScope {
    val job = launch {

      try {
        out.delay(1000.milliseconds)
      } catch (e: Exception) {
        out.info("Got exception: ${e::class.simpleName}: ${e.message}")

        // public actual typealias CancellationException = java.util.concurrent.CancellationException
        if (e is kotlinx.coroutines.CancellationException){
          out.infoBlue("it is kotlinx.coroutines.CancellationException")
        }
        // @SinceKotlin("1.4")
        //public actual typealias CancellationException = java.util.concurrent.CancellationException
        if (e is kotlin.coroutines.cancellation.CancellationException){
          out.infoBlue("it is kotlin.coroutines.cancellation.CancellationException")
        }

        throw e
      }
    }

    delay(50.milliseconds)
    job.cancel()
  }


}
