Isn't an implementation of JSR221 writing (clean room) classes in the
java.sql and javax.sql name spaces. (e.g. java.sql.Driver &
javax.sql.DataSource).

Derby is not doing that, Derby is providing an implementation of a JDBC
driver, not an implementation of JSR221 itself. Implementing JSR221 is
something that Harmony would (might) do.

My point is that the JCP rules for implementation of the spec itself do
not apply here.

My point is "implementation" of what exactly. I think Lance (JSR221 spec
lead) has already said that the TCK for JSR221 just checks the the
classes (java.sql etc.) exist and have the correct methods & signatures,
that implies to me that implementing JSR221 means providing those classes.
