Comment:
This patch seemed to solve the problem for me, but I don't really know why. How the
Java classloader works always seems a little bit like voodoo to me, so if anyone can
explain to me what the difference between
Thread.getCurrentThread().getContextClassLoader(), and
this.getClass().getClassLoader() is I would be very grateful.
