Perhaps. I want to be able to use a bean in other Spring module.
What is also an issue it that two (or more) modules obviously result in two sockets to be opened, in my case both 8400. A solution could be to open a different socket per module, e.g. negotiated with a module for that purpose that also routes traffic for a particular endpoint to the socket of the module handling that endpoint. In https://github.com/hank-cp/sbp (based on pf4j) they have a different strategy; there they have one socket for REST calls, and specific endpoints are forwarded to the appropriate plugin.
