Revision 137990

Two items:

(1) Allow the Java 1.5 to be used to build by adding:

# Specifies the source version for the Java compiler.
# Corresponds to the source attribute for the ant javac task.
# Valid values are 1.3, 1.4, 1.5.
compile.source = 1.3

(2) Refactor the multiple use of the javac/target="1.1" into a build property:

# Generate class files for specific VM version (e.g., 1.1 or 1.2).
# Note that the default value depends on the JVM that is running Ant.
# In particular, if you use JDK 1.4+ the generated classes will not be usable
# for a 1.1 Java VM unless you explicitly set this attribute to the value 1.1
# (which is the default value for JDK 1.1 to 1.3).
compile.target = 1.1
