This page is a design proposal for Java API to support VPP plugins.

## Architecture

## Main assumptions
- JVppRegistry holds a map of callback interfaces for JVppCore and plugins (generated together with JNI implementations based on provided api files).

- when API user sends a message, JVppRegistry delegates the call to JNI implementation provided by the particular plugin

- when JNI code receives reply, it asks the registry for appropriate callback interface and invokes callback method that corresponds to the received message reply

## TODO
- util.py stores workarounds for messages that are not following vpe.api naming conventions. It needs to be extensible, just in case vpp plugins have their own peculiarities
- test jvpp_gen package installation on centos7
