- render the whole line where the error/warning points to, if any, and another
line with '^', like other compilers do
- lowercase diagnostic severity
- decapitalize the message if it doesn't start with a proper name
But when running code, do it via <java> task, not via custom testing code. Most
of the time the compiled code need not be runned, because it's irrelevant to
the Ant task itself
