On Fedora 12 x86_64 with OpenJDK I get:

$ ant -v
Apache Ant version 1.7.1 compiled on August 13 2009
Buildfile: build.xml does not exist!
Build failed

and looking in ant.jar, I see, for example:

$ file org/apache/tools/ant/BuildEvent.class 
org/apache/tools/ant/BuildEvent.class: compiled Java class data, version 46.0 (Java 1.2)

so it doesn't look like the bytecode is too new.  I suggest trying to
get more information which class is causing the
UnsupportedClassVersionError and/or looking at all .class files in
/usr/share/java/ant.jar (and/or the other ant JARs).
