   Using a JSON TCP connection for what on Windows would be direct function calls (COM) or in Eclipse would be direct function calls between Java modules always felt a bit gross.

      In order to have direct function calls, you need to load the plugin's code in your own memory. Which means you expose your own memory to the plugin. Any malicious/buggy plugin could wreak havoc on your program - even managed code doesn't solve that problem in general.

      IPC is the natural solution to that - run a process in its own address space and communicate with it via I/O. TCP is not most optimal, but it is uniquous. Same thing with JSON.

      In LSP, most of the processing happens in the LSP server anyway - communication overhead between client and server is negligible in comparison to it.

         Java has had plugin isolation libraries for decades.

            Most of which run the code in a subprocess and use IPC.

               Not in my experience

                  Care to provide a counter-example?
