The Flow Framework is an abomination to engineering, and should die a pathetic death. Liberal annotations, codegen, aspect weaving and bytecode manip, requires a special JUnit test runner--it embodies all the aspects of the Java culture that I despise. I rather like the idea of SWF, but its API is too low-level, it has poor tooling, and the workflow/activity versioning is awkward and makes the systems too rigid. I am glad that AWS is moving to data-driven workflow definitions, that means they can build much better operational tooling (like the GUI) to manage and understand workflow executions.
