  classpath in the shell. I know that a shell script can do this, but I don't like
  this because everything that can be done easily in the build.xml file should be 
  there. In my opinion this avoids mixing of responsibilities.

+ If you want to avoid mixing responsibilities (and this is a good thing)
+ it makes perfect sense to define another classpath like you do, but that do 
+ not include anything from java.class.path. (plus it is a dangerous thing 
+ because paths in your classpath can be unresolved and that will fail if you 
+ fork a jvm into another directory from Ant).
+ 
+ I make a difference between what Ant needs to run and what my project needs to 
+ run. My project might need xxx v2.x only while it is not supported by Ant but 
+ only xxx v1.x. If you do a mix between Ant's classpath and yours, there, you 
+ are mixing responsabilities.
+ 
+ With complicated build it might happen that you may need ant.jar and 
+ optional.jar and other things. A typical use in my case would be to use the 
+ JProbe coverage task that runs Ant to perform all my unit tests in a single 
+ JVM. This is an extreme case and I cannot rely on java.class.path because I 
+ don't want to put the bazillion of jars that Ant needs to run all tasks and 
+ that might possibly interfer with my tests.
+ 
+ I honestly can't see where this is error prone. Unexplicit things are error 
+ prone to me.
+ 
+ Note: Make sure that <javac includeantruntime="no"...> is set when compiling.
