The failure

The test fails in its own consistency check, before it gets to testing
the real functionality.
The problem is that the test infrastructure doesn't copy the data
file, while it probably used to copy it before.
Jirko, do you have any idea what may be wrong and how to fix the test?

I am sure you didn't mean me to be the evaluator. Maybe Jirka Skrivanek ?

data/foo.xml is on test classpath but its physical location is other
than expected. It is here

openide/test/work/sys/tests/unit/src/org/openide/execution/data/foo.xml

but the test expects it here

openide/test/work/sys/tests/unit/classes/

Of course, I know.
But for the sake of test, I need the .xml file to be next to classes
or at least on the same classpath. This is the usual deployment:
have all the resources next to the classes on the classpath, as the
resources are accessed through ClassLoaders. Having it somewhere else
is broken.

So I need to setup xtest (or at leas my test) to have it there,
essentially to copy everything but .java and .form to the area of
compiled classes.

It is on the same classpath. getClass().getResource("data/foo.xml")
returns a valid URL.

Not as easy. It would take some time to change XTest. If you need it
immediatelly, please update your test.

OK, it is not enough for this test. They have to be in the same
hierarchy, as it simulates a classloader over that hierarchy.

So how can I modify the test build script to copy the file for me?
I'm not experienced in hacking the xtest infrastructure...

Actually you don't need to copy the file. You can create it in the test:
