This looks like a bug. You should never get an IllegalArgumentException
(except when invoking certain API methods incorrectly). I can't reproduce
it, though. I get this:

Error on line 7 of file:/c:/temp/test.xsl:
  XPTY0004: An empty sequence is not allowed as the first argument of
system-property()

If you can reproduce this problem, please raise it as a Saxon bug (through
the proper channels, not via this list). I'm always keen to improve
diagnostics but I can only do it if people provide feedback.
