Nit: You can pass in ScriptState rather than v8::Context.

[please use gerrit instead, 2016/03/02 01:24:34]

Done.

Use scriptState->isolate().

Done.

Have you confirmed that this throws an exception aligned with the spec?

[please use gerrit instead, 2016/03/02 01:24:34]

For PaymentResponse, the stringified JSON comes from the browser. The browser
should make sure that it's valid JSON. Therefore, this exception should not
fire. The spec does not mention anything on this topic, but it's not 100%
finalized yet.
