Reto Bachmann-Gm=C3=BCr commented on CLEREZZA-306:
---------------------------------------------

I coudn't yet reproduce the problem

added 3 lines to testSlash so that it now is a follows:

@Test
=09def testSlash =3D {
=09=09val rNode =3D new RichGraphNode(node)
=09=09Assert.assertEquals(new PlainLiteralImpl("johny"), (rNode/FOAF.nick)(=
0).getNode)
=09=09Assert.assertEquals(2, (rNode/FOAF.name).length(20))
=09=09Assert.assertEquals(2, (rNode/FOAF.name).length)
=09=09val names: CollectedIter[RichGraphNode] =3D rNode/FOAF.name
=09=09Assert.assertEquals(2, names.length)
=09=09val stringNames =3D (for(name <- (rNode/FOAF.name).elements) yield {
=09=09=09name.toString
=09=09}).toList
=09=09Assert.assertTrue(stringNames.contains("\"Johnathan Guller\""))
=09=09Assert.assertTrue(stringNames.contains("\"John\""))
=09}

is your problem reproducible? do you have a concurrency situation?
