No, you have to go through and change all of the package names of the 
classes that you move, and you have to change the includes of all of the 
files that include that package... unless you use block includes, which is 
also against the recommended style guide.

Also, if you have some products which use classes whose names conflict 
within a single sourcefile, then you have to find all instances of that 
class name and fix the package name.  EG:

  public com.mycompany.math.Vector multiplyVectors( java.util.Vector v ) {
    // ...
  }

Thankfully, Java is compiled, and the strong typing catches most of these 
problems.  Ruby is not, and I dread the thought of having to track down all 
of the bugs that will result from situations like this.
