     I concur with markspace and Martin Gregorie.  As for the
actual package name, it matters a lot less nowadays than it may
have when Java was young.  Y'see, the tools have learned about
Java and can easily "refactor" a package: Start with dboland.foo,
later change your mind and choose com.bigcompanythatboughtme.foo,
and the tools will handle the rename -- both of the renamed package
and of references to it in extra-package files.

     That, of course, assumes all the relevant sources are visible to
the tool when the rename occurs.  If you've already distributed the
dboland.foo package to umpty-leven other people who've been writing
their own code to use it, they may be somewhat perturbed when your
next patch release arrives and changes the world.  But as long as the
code is in a "pre-public" stage, dboland.whatever is fine.
