Issue Description

/Users/ckeshavabs/personal-code/rippled/src/ripple/json/impl/json_reader.cpp:928:5: warning: 'sprintf' is deprecated: This function is provided for compatibility reasons only.  Due to security concerns inherent in the design of sprintf(3), it is highly recommended that you use snprintf(3) instead. [-Wdeprecated-declarations]
