Allow duplicate keys in JSON parser#185
Merged

Conversation
The json gem emits a deprecation warning for duplicate keys in JSON objects and will raise `JSON::ParserError` in json 3.0 unless `allow_duplicate_key: true` is specified. The plugin has historically accepted duplicate keys silently (last value wins). To preserve this behavior uniformly regardless of the json gem version, this passes `allow_duplicate_key: true` to `JSON.parse`. Signed-off-by: Shizuo Fujita <fujita@clear-code.com>
