Spring seems to be deprecating it's rmi:
As of Spring Framework 5.3, support for several remoting technologies is now deprecated for security reasons and broader industry support. Supporting infrastructure will be removed from Spring Framework for its next major release.
But I can't find any easy equivalent alternative to it. REST would sound like the best choice for simple stuff, but it does not cover solutions where the task is long running and/or a contionous flow of results is needed. So the implementation would be very absurdly painful with REST. Some consider submitting the tasks via REST to queues and then possibly querying for the results separately - but this sounds like an overkill and blows the amount of work needed to sky-high for something really simple that used to be available.
Is there a good alternative or some framework that uses the non-deprecated technologies and is officially available that deals with the above mentioned problems? When something is deprecated it usually indicates that something better is available that would be the better solution, so can somebody help me on educating me what it is?
