Java prides itself in not allowing you to shoot yourself in the foot, but doesn't always live up to the hype. Recent editions have introduced powerful new syntactic tools which make development much easier, but can often result in "WAT" moments. This lightening talk (given in Reversim Summit 2016), inspired by Gary Bernhardt's famous WAT talk will showcase some of the cases where Java has left me scratching my head and asking "WAT?".
