So the type has been deprecated for at least 10 years. Rather than

to remove the file in JDK 9. A build of OpenJDK without this file
builds fine; if a build of the closed sources goes fine to, I think
that should be sufficient justification for this type to be removed.
Using code search engines, there are just a handful of references to
sun.misc.Ref in the wihld, but any such uses will have several years
to migrate to the standard java.util.SoftReference before JDK 9 ships.
Comments?
See also JDK-6852936 [1] for other candidates to remove. We've always
been a bit hesitant to remove sun.misc classes out of concern as to
what/who it might break.
As regards sun.misc.Ref then it would be good to remove it but I think
the appletviewer code needs to be checked first as it does appear to be
using it.
Another point to mention is that if do modules right in JDK 9 then the
access control rules will be extended to support encapsulation and
therefore it wouldn't be possible to link directly to JDK-internal
classes. This should allow us to be a bit more aggressive about removing
unused sun.misc classes.
