general questions about openjdk

[develop]

Hello guys,

I am just "yet another FreeBSD freak" :)

Since years I am programing in Java and my server environment is 
FreeBSD. Currently I am using diablo project but it seems it is no 
longer active. I've heard that IBM has joined OpenJDK project and this 
is really good sign.

I am wondering how far is the development of openJDK6 and especially is 
the project mature enough to be used on productive environment?

Are there "gaps" into APIs, specially into implementation of .nio and 
.concurrency packages?

Thank you for your feedback.

Cheers
