Ant version upgrade to 1.7.1?

Hi everybody,

For the newest version of hsqldb 1.9.0 I would need ant version 1.7.1 or 
later. Currently 1.6.2 is used.
Would it be possible to do this upgrade or is there anything I have to 
take into account like configure or something special nobody never 
thought off.

I haven't set up any cws currently, I would like to collect the pitfalls 
  first before starting ;-)

Projects which use Ant so far are:
- rhino
- jfreereport
- saxon
- configure.in
- tomcat
- xmerge
- hsqldb
- scripting
- apache-commons

That's what OpenGrok told me.


Best regards,

Ocke
