This version introduces parallel execution of tasks within the same target. Several new tasks have been added or enhanced - javac now supports a wider range of implementations out of the box, just as well as ejbjar and rmic. A new task named condition can be used to employ boolean logic to combine multiple conditions, instead of the multi target constructs one had to use in 1.3.
Apart from bugfixes, enhancements of existing tasks, and a couple of new tasks,
this release introduces the concept of parallel execution of tasks inside the
same target.
