This approach works fine for me as in:

  Source src = new StreamSource(new StringReader("<Urmel/>"));

The exception seems to occur in a large program. There must be something
wrong in those lines that you haven't shown. Rather than posting the
massive program, try boiling it down to a small, self-contained test
case. If the error persists, you might want to post the small test
program.
