I suspect that HTTP/308 was just not a thing 14/15 years ago, but no clue whether it’s just not been implemented all the time or whether there was a reason to not handle it at all in HttpURLConnection. I could not find anything useful in the OpenJDK commit log nor in the OpenJDK JIRA (there was a ticket about the Webstart client).

The history you can observe probably dates back to the time when
Java was open sourced, but the networking code is probably older
than that.

I would guess that 308 was never implemented.
Do you have an account for https://bugs.openjdk.org/ ?
If you do please log an RFE (component core-libs, subcomponent
java.net) and we will evaluate it. Otherwise you can log
it through https://bugreport.java.com/

I see that 308 is not very different from 301 except that it
explicitly prevents turning a POST into a GET on redirection - so
there may be several places to tweak in the HttpURLConnection code
if we decided to implement this.
