> Profiling revealed some allocations that are easy to remove:
> * The HotRod operations factory stores a list of flags in a thread-local. The thread-local can be removed, and the flags can be stored in an {{int}}.
> * JGroupsTransport copies the list of members to check if a broadcast should be sent as a unicast, and the copy is then discarded.
> * ExtendedByteBuf could use {{Array.empty}} instead of {{Array[Byte]()}}.
> * DecoratedCache could avoid calling {{Arrays.asList()}}.
