This is a special-case API designed only for use by the jlink tool, which read the raw jimage files. It is not the correct API for accessing jimage resources at runtime.
This API ignores the previewMode of the ImageReader from
which it is obtained, and returns an unmapped view of entries (e.g. allowing
for direct access of resources in the META-INF/preview/... namespace).
It disallows access to resource directories (i.e. "/modules/...")
or packages entries (i.e. "/packages/...").
Use the ImageReader API to correctly account for preview mode at
runtime.
Implementation Note
This class needs to maintain JDK 8 source compatibility. It is used internally in the JDK to implement jimage/jrtfs access, but also compiled and delivered as part of the jrtfs.jar to support access to the jimage file provided by the shipped JDK by tools running on JDK 8.
