João Cabrita commented on BEAM-5723:
------------------------------------
This seems to be happening because guava is repackaged but the cassandra
drivers aren't.
Looking at the decompiled JAR, it seems the call to mapper.saveAsync is changed
to return the repackaged ListenableFuture class but, at runtime, the unchanged
cassandra mapper is used, which has no clue where that class comes from...
