It's time to bring these changes into jdk9/dev. The issue to bring these changes into jdk9/dev in bulk has been approved via the FC extension process (still in use during JDK 9 RDP2).

Should the @return for ModuleDescriptor.Requires::rawCompiledVersion contain

  * @return The string containing the version of the module if recorded
  *                at compile-time, OR AN EMPTY OPTIONAL IF NO VERSION WAS RECORDED
