Sun classes imported by Derby code

[Rick Hillegas]

As an experiment, I built Derby using the Apache Harmony jars instead of 
the jdk14 libraries. When I did this, I discovered Derby references to 
classes in packages under com.sun.tools. Those reference appear in our 
javadoc Taglet classes under java/build/org/apache/derbyBuild/javadoc. 
This seems unclean to me. I would welcome advice about how to handle this.

Thanks,
