EMF model generation

Yesterday I tried to use Eclipse EMF plugin and generate some model from XSD file. I got official library.xsd file from EMF developers and fresh new emf release version. When I tried to generate model, I have got this NullPointerException. I spent about four hours installing different versions of eclipse and different versions of EMF pluging before I mention this paragraph about this problem in XSD generation tutorial.

It is well known problem, and main problem is in this sun jdk 1.4.2! Damn, I didn't see this coming.
