Please tell us about your environment: client : cpp rmq console: from externals os: centos 7.4 3. Other information (e.g. detailed explanation, logs, related issues, suggestions how to fix, etc): cpp log: 18:54:41.319764](info):topic:%RETRY%ai-high-level-processor, group:ai-high-level-processor, timestamp:1555325640000, isForce:0,isForce:false [2019-Apr-15 18:54:41.319815](error):ResetOffsetBody::Decode fail [2019-Apr-15 18:54:41.319828](error):resetOffset failed as received data could not be unserialized [2019-Apr-15 18:54:41.321733](info):topic:%RETRY%ai-high-level-processor, group:ai-high-level-processor, timestamp:1555325640000, isForce:0,isForce:false [2019-Apr-15 18:54:41.321776](error):ResetOffsetBody::Decode fail [2019-Apr-15 18:54:41.321789](error):resetOffset failed as received data could not be unserialized **FEATURE REQUEST** my analytics: my guess: from cpp log we can see , cpp can not Decode resetoffset command body from broker. maybe broker send with wrong encoding. check guess: resetoffset command process: console (java) -> broker --> client step 1. broker choose java-format to encode resetoffset body  step 2. cpp decode body with cpp-format, absolutely fail　 how-to-fix: when console call broker to resetOffset, console must know what client-languages for all-connected-client, so send resetOffset use the RIGHT-LANGUAGE to call broker. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
