why is the Sun Binary license file included in the sources on this site?

Do I understand correctly that if I download and build the JavaHelp
sources from this site
(http://java.net/projects/javahelp/sources/svn/show/tags/2.0_05/jhMaste
r), then my JAR would be under a GPL license?

If that's so, then why does the jhMaster/JavaHelp directory contain a
LICENSE.html that describes the Sun Binary license?
Here's the license:

ster/JavaHelp/LICENSE.html?rev=89)
