With the version: `jdk8u172-b11`  With the version: `jdk8u202-b08`  After briefly debugging, we found that the time was lost between Controller->Invoker & Invoker->Controller (as reverting version already helps to improve the problem there seems to be an issue with the communication with kafka). We didnt find a quick solution so reverting back to the old version, and in the meanwhile will continue to look for the root cause. ## Related issue and scope <!--- Please include a link to a related issue if there is one. --> - [ ] I opened an issue to propose and discuss this change (#????) ## My changes affect the following components <!--- Select below all system components are affected by your change. --> <!--- Enter an `x` in all applicable boxes. --> - [ ] API - [x] Controller - [ ] Message Bus (e.g., Kafka) - [ ] Loadbalancer - [x] Invoker - [ ] Intrinsic actions (e.g., sequences, conductors) - [ ] Data stores (e.g., CouchDB) - [ ] Tests - [ ] Deployment - [ ] CLI - [ ] General tooling - [ ] Documentation ## Types of changes <!--- What types of changes does your code introduce?
