fix #757

maybe scala/scala#7270 ? 🤔

package example

import scala.reflect.NameTransformer

object A{
  Main.a = 1
}

object B{
  Main.b = 1
}

object Main {
  var a: Int = 0
  var b: Int = 0

  def initializeByConstructor(): Int = {
    this.a = 0
    val List(constructor) = Class.forName("example.A$").getDeclaredConstructors.toList
    constructor.setAccessible(true)
    constructor.newInstance()
    val result = Main.a
    this.a = 0
    result
  }

  def initializeByMODULE_field(): Int = {
    this.b = 0
    Class.forName("example.B$").getDeclaredField(NameTransformer.MODULE_INSTANCE_NAME).get(null)
    val result = Main.b
    this.b = 0
    result
  }

  def main(args: Array[String]): Unit = {
    println((A, B))
    println(scala.util.Properties.versionString)
    println(initializeByConstructor())
    println(initializeByMODULE_field())
  }
}
