A few questions for thought: - Is the API transition from 1.x to 2.0 fairly easy? - If a single web application depends on two pieces of "third party" software, one using 1.x and one using 2.0, will that web application be totally screwed? - Is there a simple way to make migration and coexistence easier? Would changing the package name be that way?
Having faced many of these type of issues from the user side (since I work on stuff that basically integrates as or into Java web applications), anything we can do to make coexistence easier is a big +1. On the flip side, changing package names is pretty ugly.

I can see your logic as to how someone might end up with incompatible versions, but I don't, at this point, want to change the package names. 2.0 has been under development for a year, and I've advertised it on the user list, incompatibility and all, on several occasions. No one has raised this issue. Anyone who runs into this can always use classloader technology to achieve isolation. I won't claim that this would be painless. As an example of another ASF project, I think that commons-http client has not changed package names as they have gone through several major versions of incompatibility, though I could be confused. Obviously, it would only take me about a day to change the package name, so if there are a bunch of people who agree with you, I'll capitulate. Let's see what other people think.
