It's because the source of Hibernate is not a citizen of a Java project.
Eclipse is just being convenient by showing you the source, because the
library is really a JAR.

You could make it a linked folder to your application project, but that
is probably going to create more headaches. What I would do (have done,
in fact, with a different third-party library) is to create a separate
project for that library's source code, and import it (or use a linked
folder). Then you can configure that project's build path and compile
options so that you can effectively edit the code and run the Ant script
to build it into a new JAR.
You'll either have to copy your modified JAR over into your own app, or
make your app project depend on the Hibernate project instead of the
Hibernate distrib JAR.
