No. Every EULA you'll click through will include some clause restricting usage to 30 days for evaluation purposes, except in a few cases (db client, beta versions, XE edition, Technology Network stuff, Linux etc). And they do enforce that clause as soon as they find you're using any of their stuff. Plus, you need an account on their site to download pretty much anything, so they'll know what you download, and from time to time you might get a call to see how that "reviewing" is going, especially if you are not a customer yet.
It makes it very easy for people to get access to software and to learn, however, especially if they're covered by a company who is already a customer.
How does that play with the fact these changes seem to be checked into the GPL'd code? Wouldn't GPL itself give you a separate license to use the features regardless of whatever EULA Oracle comes up with?
