You must not forget that parts of Ant have been written at a time where
Java2 was too new to require it as runtime environment.

Yes, there is.

Just now we have voted to accept Java5 (yes, 5, not 7) as our minimum
requirement for Ant's trunk following the upcoming 1.8.3 release.  This
means we can not use Java7 features directly.

One approach that may be possible is to write a FileUtils replacement
using Java7 features.  Almost all file system interactions of Ant go
through FileUtils and Ant's core could detect at runtime whether Java7
is around and use the matching FileUtils class.
