Bad checksum problem building jdk17 on 7.2-R

[Joshua Tinnin]

Trying to build jdk16 on 7.2-R, and am getting this error:

gamera:/usr/ports/java/jdk16:# make install clean
===>  Vulnerability check disabled, database not found

As you can see, I do have jdk-6u3-fcs-src-b05-jrl-24_sep_2007.jar, but
the checksum doesn't match. I downloaded it through the link:
http://download.java.net/jdk6/6u3/promoted/b05/jdk-6u3-fcs-src-b05-jrl-24_sep_2007.jar

In fact, I downloaded it three times now, and it still fails the
checksum.

If I clear distinfo, this is the error I get:

[/usr/ports/distfiles/jdk-6u3-fcs-src-b05-jrl-24_sep_2007.jar]
  End-of-central-directory signature not found.  Either this file is not
  a zipfile, or it constitutes one disk of a multi-part archive.  In the
  latter case the central directory and zipfile comment will be found on
  the last disk(s) of this archive.
unzip:  cannot find zipfile directory in one of
/usr/ports/distfiles/jdk-6u3-fcs-src-b05-jrl-24_sep_2007.jar or

Where can I find a valid source file? I've been trying to build this for
days and am about ready to call it quits. Am spending far too much time
trying to chase down issues and my work is suffering.


And it's impossible to find the version of the tzupdater required by the
port on Sun's site, so it has to be retrieved elsewhere. Luckily, the
checksum is OK, but the distribution of that file is hardly reliable.
