 * There was a problem determining which VM to use for generation-1
 * This is because the way Java is handled on Gentoo has drastically changed.
 * There does not seem to be a 1.4 or 1.3 JDK installed.
 * You should probably install =virtual/jdk-1.4* or =virtual/jdk-1.3*
 * It is important to have either a 1.4 or 1.3 JDK installed
 * in order for the old and new Java systems to coexist
 * Details about this can be found at:
 *      http://overlays.gentoo.org/proj/java/wiki/Why_We_Need_Java14

 * You should run, and follow the advice of:
 *      /usr/bin/java-check-environment
 * You will also likely want to follow the Java Upgrade Guide:
 *      http://www.gentoo.org/proj/en/java/java-upgrade.xml
 * If you have problems with the guide, please see:
