Hi all,

I guess, you have noticed, that since some time I'm working on enhancing the JDK's charset de/encoding: https://java-nio-charset-enhanced.dev.java.net/.

Dalibor Topic and Martin Buchholz have suggested to create a new OpenJDK 7 project to make those enhancements available for OpenJDK 7 under GPL.

It should cover following topics:

enhancing performance
reducing disk-footprint
reducing memory consumption
discussing different strategies to serve differing frequency of occurrence of characters in charsets
discussing coder result accuracy against compatibility of legacy behaviour
extending functionality, e.g.:
- adding short cut methods to speed up direct array access
- adding short cut for replacement coders
- adding methods to terminate the decoding on occurrence of exclusive cipher. See: Bug 6695386
providing wrapper to replace converter classes from sun.io package

The project should be a clone from jdk7/tl/jdk tree.

In near future there should be a survey about launching this project.

Regards,

Ulf Zibis
