> Creates a new, narrowed API explicitly for use by jlink, which view the 
> resource entries in a jimage file without the re-mapping of names and 
> invention of synthetic entries inherent in ImageReader.
> 
> Another good reason to express this new API as something other than 
> ImageReader is that, to fix issues such as 
> [JDK-8357249](https://bugs.openjdk.org/browse/JDK-8357249), we don't want to 
> have the (System)ImageReader class used directly in jlink code. It's just the 
> wrong abstraction and will make it harder to refactor jlink to use a 
> non-singleton API with a controlled lifetime later. 
> 
> I've not added unit tests for the new API (yet), but the fact the 
> PackagedModulesVsRuntimeImageLinkTest passes with preview content in the 
> jimage file means that it's working as expected.
