I've tried exactly the steps you've listed and it works perfectly here. I can delete top level resources, folders and
resources from folders. But I tried with H2 because Mysql is a little more effort here. Before I test with Mysql, can
you pease confirm that it works for you with H2 (just to exclude other differences in your setup)?

Following the steps, if you remove a root element sometimes the exception is not raised, but you can see how the element is marked as Invalid in the CDO View, and if you try to operate with this resource, you only get a lot of exceptions. This does not happen if the removed element is contained into a folder. Maybe you don't get this exception cause the code is treating the exception, but it is raised.
I try it with MySQL 5.5.27, PostgreSQL 9.1.8 and PostgreSQL 9.2.3. I'll try it with H2 as soon as possible and I will tell you the results, but I thing that it will be the same...
