I'm quite unsatisfied with the current handling of character sets in the build in general. :-( I'd really like to modernize it. I have a, slightly fuzzy, laundry list of things I want to fix from a build perspective, but I'm not sure of what "external" requirements are coming from AIX and the general core-libs agenda regarding character sets in general.

I think there is a good opportunity to solve many problems at the same time here, as long as everyone agrees on what is the preferred outcome. The support in the build to configure the charsets to include in java.base on each platform has been working well. Charsets that aren't in java.base go into the jdk.charsets service provider module and that has been working well too. From the result point of view, perhaps, but definitely not from the build perspective. ;-) But yes, I understand this is functionality that should be kept. One thing that we lack is some way to add charsets for specific platforms and this comes up with the IBM patches where they are looking to adding several additional IBM charsets. One starting point that we've touched on in several threads here is dropping the EBCDIC charsets from the main stream builds. Going there will need build support. So build support for trivially adding specific charsets to specific platforms? Both to java.base (for AIX) and jdk.charsets, I presume, then?

Can you expand on the issue of dropping ebcdic? What's the problem that needs build support?
