* The problem was that cache instance was instantiated on different Mistral instances and invalidation didn't work properly (known problem for local cache implementations). The solution, first of all, is to cache specifications by workflow execution ids so that we get a consistent spec value during workflow execution lifetime. And secondly, if we need to build a specification based on workflow definition id we also need to use 'updated_at' as part of cache key so that if workflow definition has changed the cache is updated properly. Old cache entities would be kicked out of cache by LRU algorithm as the cache runs out of space. Change-Id: If97b2e47d8adcbd7b5d5844b56e24eac1b1ae6c1
