1.) You are right, it's not as simple as I thought first, having 
Base/Abstract-X-coder. Maybe there is a Chance by generifying Charset 
and Charset-X-coder.

2.) To implement the 4-way x-codeLoop() methods for general use for all 
sun.nio.cs charsets sun.nio.cs.Base/Abstract-X-coder is the only way, so 
why introduce additional interface. There also constants like MAX_ASCII, 
MALFORMED_EXCEPTION, etc. could be hosted. See:
