netty trunk maven build error

Hi:

Netty is not new to me because several years ago I know Trustin wrote netty  but later on he got involved in apache mina. Yes, apache is a good brand to attract new developers, but apache model is not one-size-fit-all. And most importantly it is the project leader who build a harmonious community which decide the direction of a project. I think Trustin did a good job on this thing and he will keep doing it. Right now netty is coming back but it is a new one. Anyway, welcome back, netty!

I am evaluating nio frameworks to start a new project. I think the clean API of netty and its promising performance is exactly what I want. I have read the performance page on netty website and I also have a look at benchmark project. I am wondering why there is no latency figures? Throughput is just one of all determinants.

Another problem is that, I got an error when I execute maven goal "package". I turned on the maven debug option and get this error stack. It seems jdocbook plugin is trying to open remote stylesheet file by ftp.

thanks

yanky
