Generated vpp-japi (part of VPP project) today is asynchronous and works, but there are some drawbacks:
Not really asynchronous from Java perspective, requires Java to perform active wait loops (for all generated functions) – big overhead due to JNI boundary being crossed lots of times Requires hand crafted implementations for dump calls The japi should be:
Truly asynchronous with callbacks into Java Lightweight (no caching in the C code, generate all the methods except connect, disconnect and ping etc.)
