Jdeprscan warning with --release 8

I have a standalone Java-9 based project with one class on which I experimented with a tool moved over the Java SE release, when I ran the same using version 9 in my project, there were no logs in the console (assuming that this is the expected behavior): Main.java jdeprscan

➜  standalone git:(master) ✗ jdeprscan --release 9 .
Directory .:

means there were no legacy APIs used by code that just seemed to me.

Then I tried the same with release 8, although I didn’t get any Deprecatedagain, but the console showed certain warnings for the project:

➜  standalone git:(master) ✗ jdeprscan --release 8 .
warning: unknown enum constant javax.jws.WebParam.Mode.IN
warning: unknown enum constant javax.jws.soap.SOAPBinding.Use.LITERAL
warning: unknown enum constant javax.annotation.Resource.AuthenticationType.CONTAINER

Q: Why is there a warning with version 8 and not version 9? To add to the details here, for example. in JavaSE8 is WebParam.Mode.INnot marked as deprecated.
