I ran into a small problem when running the ant script 
under java 1.5. Specifying target to 1.1 with javac 1.5 
without also specifying a source code format is an error. 
This is because the source parameter defaults to 1.5 
which requires that the target is also set to 1.5. The ant 
docs recommends that you always specify both the 
source and target attributes anyway, to avoid java 
version dependent defaults. This patch adds the source 
attribute to all javac and javadoc elements. The value is 
set to 1.2.
