The size of on-heap or off-heap stores should not be changed during a shutdown. If the amount of memory allocated is reduced, elements will be evicted upon restart.

Restartable caches should not be removed from the CacheManager during a shutdown.

If a restartable cache is disposed, the reference to the cache is deleted, but the cache contents remain in memory and on disk. After a restart, the cache contents are once again recovered into memory and on disk. The way to safely dispose of an unused restartable cache, so that it does not take any space in disk or memory, is to call clear on the cache and then dispose.
