Yu wuz right, re RAW Camera Update 3.12:
Even though it pointed to 3.11 (which, strangely enough, seems to have disappeared from the Support Downloads page), downloading it produced the correct update.

In my case, 7.6MB took 15.5 minutes to download; the last 1MB took 235 sec to download = 4.2 KB/sec.

So, I'm going to wait to get to a high-speed access to download the 'new' Java 2012-002 (if only to see how it might differ from the Java 2012-001 which I installed the other day).
