You seem to be running a custom Ant task that in turn invokes the
<java> task nested into multiple levels of <antcall> tasks internally
which makes debugging this quite a bit more complex.

For the benefit of those who don't want to install OpenOffice just to
see the logfile ...

The line in question is the put invocation in
Properties p = new Properties();
for (Enumeration e = sys.propertyNames(); e.hasMoreElements();) {
String name = (String) e.nextElement();
p.put(name, sys.getProperty(name));
}
I think this is the same problem we've already seen in a different
place <https://issues.apache.org/bugzilla/show_bug.cgi?id=42334>.
I'll fix it in trunk, but it may be too late for 1.7.1.
Could you run your task outside of a JEE container?
