[infinispan-dev] Where is the LegacyLoaderAdapter interface ?

Hello guys, I'm updating myself since the cache store have been split into different projects. I have forked the infinispan-cachestore-monogdb and I can't find an interface org.infinispan.configuration.cache.LegacyLoaderAdapter Does it have been deleted ? Replace (by what) ? Must / should the MongoDB cache store been updated ? Thanks Guillaume
