Hyphenated company name in Java packages

Say you're working on the core module of the foo project for BarBaz Incorporated. Your code fragment might look like this:

package com.barbaz.foo.core;

import com.barbaz.foo.util;

What would the convention be if your company's website was not barbaz.com, but instead bar-baz.com?

Solution 1:

The SUN-era Java Language Specification gives a suggested convention:

If the domain name contains a hyphen, or any other special character not allowed in an identifier (§3.8), convert it into an underscore.

But it's just a suggestion...

Solution 2:

I just looked through my browser's history, and in the last 2 months I haven't visited a single domain with a hyphen. So the convention is to rename the company.

Alternatively, leave out the hyphen, because BazBaz won't ever include Baz=Baz's code in their own.
