Hi,

I've created a branch in vertx-infinispan to start incorporating the new features in 9.2.

https://github.com/vert-x3/vertx-infinispan/tree/ispn92

Here are a couple of comments/concerns on MultimapCache:
1/ EmbeddedMultimapCacheManagerFactory#from returns a raw MultimapCacheManager; it would be nice to have type arguments instead, to avoid unchecked assignment warnings
2/ MultimapCache does not accept entry listeners. We use them to build a near cache to increase the speed of sending

1/ is easy, but do you think 2/ could be added in 9.2?

Thank you,
Thomas
