Issue:

1. XTypeName is super class of XClassName
2. The companion object fields (compiled into <clinit> method) invokes sub class XClassName initialization through .asClassName
   1. val BOXED_BOOLEAN = Boolean::class.asClassName()
   2. val BOXED_BOOLEAN = Boolean::class.asClassName()
   3. val BOXED_BYTE = Byte::class.asClassName()
   4. val BOXED_SHORT = Short::class.asClassName()
   5. val BOXED_INT = Int::class.asClassName()
   6. val BOXED_LONG = Long::class.asClassName()
   7. val BOXED_CHAR = Char::class.asClassName()
   8. val BOXED_FLOAT = Float::class.asClassName()
   9. val BOXED_DOUBLE = Double::class.asClassName()

Real Case:

• https://b.corp.google.com/issues/366982995

  • The can be XClassName, a helper class, or a top-level class.
