Recently i faced this Exception while working on a basic spring example...later to my surprize it turned out to be one stupid experience ;-) ...thus thought of sharing the same with an intent that it could save someone else's time...

It's an Eclipse bug, I've noticed it too. Make sure that you're running the right Eclipse Runtime config (i.e. if you're clicking on the little green "Play" button on the top, thinking it will re-run the last (valid) Runtime you've ran, re-check (by clicking on the down arrow next to it) to make sure no new Runtime has been created).
What I've noticed it that even though I create a perfectlly valid run-time pointing to a Java main class and everyting, which I run a few times and all is ok, after a while, if I select an xml file (because I wanted to edit it for example) and then leave it selected as I click on my run button, Eclipse will create a new XSLT Transformation run time for that xml file and try to run it, failing with the exception you report. The solution is to erase that run time, make sure I have no xml file selected, and re-run the correct run time.
