FileUtils to select (Martijn's approach is
ridiculously insane enough to have captured my fancy
;) ), it must also take into account whether the
desired classes are available, falling back to the
basic impl. otherwise.
I'm coming round to think that Martijn's approach would be the least
disruptive to the code base - simply as the delegate approach wouldn't
mean recoding all tasks to use an interface instead of an
implementation. This reduces the effort a lot and would make it less
likely that errors would creep in. Definitely my +1 for the delegate
approach, +0 for the interfaces and factory approach (ie if for some
reason we can't do the delagate approach, the interfaces should be
reconsidered)
Thanks
