The tzupdater used was the latest one downloaded from Oracle's site (2.2.0).

I modified the asia file to have this line:

Rule	Japan	1948	1951	-	Sep	Sun>=9	1:00	0	S

I was able to succesfully patch JDKs 1.8.0.181, 10.0.2, 11-28.

Though I'm not exactly sure how I would verify that the change is 
actually correct.
