The disk drive organization in most Java implementations matches the package 
organization, rooted at a directory mentioned in the class path.

Irrelevant, as others have told you. Use the domain you would have if you had one.

Who says you have to have a commercial organization to have a domain?

Who told you you had to have a domain to use it as your package name? The only rule
is that you cannot use someone else's.

The first element should be a top-level domain, like "com".

Do not use the word "java" in your package names. What's the point? If it isn't 
Java it isn't in your Java program. Also, "Java" is trademarked.

What exactly do you fear?

What evidence led you to that concern?

Huh?

Java programmers don't "like" anything. We do what the platform calls for.

Is "src" in your classpath or sourcepath?

Is "class" in your classpath or sourcepath?

The first element of your package name by convention should equate to a TLD.
Use "com", typically.

Don't use "class" or "package" or "java" or any garbage like that in your package names
unless there is a specific semantic to the use of the term. The fact that there are classes 
in a package does not need reinforcement in your names. It only serves to add clutter to 
do that.

What does the documentation suggest you do?
