Going to the page this ebuild refers to (this ebuild is still a dependancy of blackdown-jdk-1.4.1 when use doc is in effect) says sun moved it into the archive. The file is still accessible, but could we get more current versions of things in use? * Please download j2sdk-1_4_1-doc.zip from http://java.sun.com/j2se/1.4.1/download.html and move it to /usr/portage/distfiles Version 1.4.1 Software Products listed on this page have completed the Sun End of Life process. Users should upgrade to current product versions. These products are no longer supported by Sun. For developer requirements, all products that have completed the EOL transition period have moved to the Archive area.
Fixed in portage to point to the new location for the docs due to Sun's EOL crap.
