# Stage 4: Decide the exact JDK version if only a minimum version is specified

# 1.4, depending on what JDK's are already installed. The FreeBSD JDK will be
# preferred. The Sun JDK 1.4 for Linux is always the least preferred JDK.
# However, the most respected rule is that if a JDK is already installed, then
# no JDK will be downloaded unless necessary.
#
# The following rules will be used, per setting:
#
# If the setting is 1.1+, then use an existing 1.2 or 1.3 JDK if installed,
# otherwise use the JDK 1.1.8 for FreeBSD if it is already installed. If no
# other JDK than the Sun JDK 1.4 for Linux is installed, then that one will be
# used. It is the least preferred alternative.
#
# If the setting is 1.2+, then use an already installed 1.2, 1.3 or 1.4 JDK.
# If there is no such JDK, then set USE_JAVA to 1.2. An 1.3 JDK is preferred
# over 1.2 JDK's.
#
# If the setting is 1.3+, then see if the Sun JDK 1.4 for Linux is installed,
# while no 1.3 JDK's are installed. If that is the case, then USE_JAVA will be
# set to 1.4. Otherwise it will be set to 1.3. All 1.3 JDK's are currently
# preferred over a 1.4.x JDK since it is considered less stable.
#
# If the setting is 1.4+, then set it to 1.4 right away. There is no other
# option at the moment.
