when return request token (i server), send values in body of response: oauth_token=946ccd316c&oauth_token_secret=395cfee8ca&oauth_callback_confirmed=true i trying figure out if it'd possible dance on jsonp . signing , requesting works fine, body isn't json, response fails during parsing. so, reply body coded jsonp insted (if client requested it), this: callback({oauth_token:'946ccd316c',oauth_token_secret:'395cfee8ca',oauth_callback_confirmed:true}) and work. questions are: would break standards? allowed change encoding of body? there better way? oauth specification doesn't specify format sending token. think return inside json object have shown. in fact google returns access_token inside json object shown below: response :{ "access_token" : "ya29s6zqbibqpa5rz8oty00xj-xydfdfddteerer-1em", "token_type" : "bearer", "expires_in" : 3600 }

i have come across seems peculiarity in javafx api: longproperty implements property<number> , not property<long> . what reason this? sort of idea stems java's inherent problem covariance , contravariance, because generics implemented stupidly via erasure, maintain backwards compatibility bytecode; problem have arisen having longproperty implement both property<number> and property<long> ? edit: question originated problem: apply longproperty tablecolumn programmatically (vs semantically) it can't implement both. to that, need implement 2 versions of each method in interface uses generic. let's take 1 example: bindbidirectional(property<long> other) { ... } under hood, erasure means gets compiled down to: bindbidirectional(property other) { ... } so then, implements property<number> , property<long> do? have 2 methods: bindbidirectional(property<long> other) { ... } bindbidirectional(prope...
