 * === Java Environment Checker ===
 * The purpose of this script is to check the sanity of your Java Environment.
 * We have significantly changed and improved the way Java is handled in many respects.
 * Please refer to http://www.gentoo.org/proj/en/java/java-upgrade.xml for details

 * Checking vm_environment_files ...                                      [ ok ]
 * Checking user_settings ...                                             [ ok ]
 * Checking generation_1_system_vm ...
 * No Generation-1 System VM is set! (no /etc/env.d/20java)
 * It doesn't look like java-config-1 sees any installed VMs.
 * It is most likely because you don't have a 1.4 JDK installed
 * This is required for generation-1 to work properly.
 * You will want to emerge =virtual/jdk-1.4*                              [ !! ]
 * Some problems were found. Please follow the instructions above, and rerun java-check-environment
