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. 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.
