JSON loading exception when starting Consumer in broadcasting mode

Last Updated: Feb 24, 2018

Possible causes

Fastjson’s version is too old, which causes exception when a broadcast Consumer loads the local offsets.json file, and failure to start the service.

Suggested solution

Upgrade Fastjson to the version on which the ons-client is dependent, to make sure the local offsets.json file can be loaded successfully. The offsets.json is stored at /home/{user}/.rocketmq_offsets/ by default.
