The bulk operations which are part of JSR-107 are not supported in the current Cache API in 10. This was done to make it easier to be compatible with existing code and with distributed caching systems, however, it looks like pretty much every distributed cache supports bulk operations and they are typically substantially faster so adding those into the API would likely help with performance when they are used in the future.
This is also needed to make the new security cache more efficient.

void putAll(java.util.Map<? extends K, ? extends V> map);
void removeAll(Set<? extends K> keys);
