Ha - whatever OSS licences say, when you're dealing with terms written by Oracle lawyers, you're getting even less chances of successfully suing them if it goes wrong. You can argue about their technology, but the legal part of Oracle is quite capable, so much that I would assert that Citibank does not have a case against Oracle no matter what the software did. Pretty much all commercial software contracts includes similar idemnification clauses - they can't include the "not fit for any purpose" but the "if it goes wrong, it's not our problem" part definitely is there; and if it turns out to be not fit for purpose (which is ridiculously unlikely to prove for any actual product that's not totally made-up-nonexistent-fraudulent thing) then you might get back some of what you paid for it, but not for the losses you had due to it failing, assuming the licence/contract wasn't written by incompetent idiots.
