Hello.

Could you review the fix ?

Bug: https://bugs.openjdk.java.net/browse/JDK-8212794 Change: https://cr.openjdk.java.net/~itakiguchi/8212794/webrev.00/

I'd like to obtain a sponsor for this issue.

IBM964 charset and IBM29626C charset are required for default charset on AIX zh_TW and ja_JP locale. OpenJDK already has IBM964, but it could not be configured for default charset. IBM29626C is new one. (IBM33722 extends IBM29626C class)

I knew IBM charsets would need to move to somewhere. The discussion was started by "Adding new IBM extended charsets". [1] But it's related default charset issue. Please put them inside of OpenJDK.

About IBM964, Bhaktavatsal started the discussion [2]. Sherman said that [3] the new model (open/make/data/charetmapping), instead of hard-coding the map into the source code.

This fix only has small sized hard-coded mapping, IBM964/IBM29626C/IBM33722 refer other charsets conversion table which are using the new model. And class file is smaller then before. Still I used SimpleEUCEncoder class because it's stable. I think we may re-write it by IBM charsets renewal.

Thanks, Ichiroh Takiguchi IBM Japan, Ltd.
