A bare-bones Java RPC framework with client and server implementations, seemingly written as a teaching exercise. It's for developers working through design patterns or RPC concepts from scratch, not for anyone building something real.
- The structure is minimal enough to actually read and understand in one sitting — no framework magic hiding the core mechanics.
- The client/server split with a demo calculator service makes the request/response flow concrete and traceable.
- Forks outnumber stars proportionally high, suggesting people are actually using it as a starting point for their own implementations.
- The README is empty. There is no explanation of what this does, how to run it, or what design patterns it's meant to demonstrate.
- Last commit was February 2020 — five years abandoned, which matters for a teaching repo because anyone hitting a bug or question gets no help.
- 225 stars for a Java RPC framework with no documentation or build tooling (no Maven, no Gradle, no jar) means the ceiling of usefulness is a single afternoon of reading.
- No error handling, no serialization abstraction, no connection pooling — fine for a toy, but the repo gives no signal about where the intentional simplification ends and the incompleteness begins.
