Are there many changes in Sarge?
At this moment, there only seems to be dh_javadoc, which is a tool in the gjdoc package. However, people spoke about other tools on the debian-java mailing list in 2003. The Etch release was the first one to provide Sun’s JDK environment without the need to download it from third-party repositories (see Java 5 and 6, Section 6.3.1).
