    • State changed from “new” to “invalid”

    This is an invalid JSON object. JSON key/value pairs are required to be enclosed in {}, and JSON Arrays are required to be enclosed in [].

    That was a typo. The JSON string, as is in the test, should be:

    {"a" : "1"}

    I believe that the ActiveSupport JSON parser will fail for any value which ends in "".
