Bug#570588: ant -diagnostics returns with error code != 0

[Matthias Klose]

Package: ant
Version: 1.8.0-1
Severity: serious

The openjdk-6 build fails with:

ant -diagnostics now return with 1, not with 0 as in ant-1.7. I don't see any 
documentation that this change was intended. severity serious because it's a 
regression and breaks existing builds.
