still working on 5-6 upgrade
As someone still working on a 5 to 6 upgrade project that is now measured in man years, literally. This is great news.
Given that jboss no longer supports remote java calls across different versions of the server any talk of microservices should be taken with a pinch of salt. It's not really a microservice arch if you are obliged to upgrade all the parts all at the same point in time, it's just one big component based macroservice running in multiple vms.
