jtreg is not self-contained but is a set of extensions for 
which is the harness used for Sun's conformance test suites and other 
Therefore, including the jtreg source code in the JDK repositories would 
push the problem back one step -- you'd still need to download the JTHarness
source code.

I don't see why this is an issue for the Linux distros in particular, 
since it is
generally very easy to install any necessary packages, with apt-get and 
tools. Is there any reason why it is not equally easy to install jtreg 
the same way?
