An alternative is to really implement the singleton pattern in ECP, however given the existing mechanism we have in Charset.java and the "hacky" init() implementation we need in ECP, I go with the current approach. http://cr.openjdk.java.net/~sherman/8012326/webrev I'm not sure that I understand your comment, are you saying that the initialize-on-demand holder idiom wouldn't work here? I would think it should make it simpler and easier to understand.
For the ISO2022_JP_2 and MSISO2022JP then they probably don't need to be volatile. As it stands then the fields may get written more than once (which is harmless).
