Vladislav Novikov updated IGNITE-25496:
---------------------------------------
Description:
When calling the {{restoreSnapshot(String name, @Nullable Collection<String>
cacheGroupNames) method with a }}non-serializable collection {{{}({}}}e.g.
{{{}HashMap.keySet()){}}}, the operation fails with
{{{}NotSerializableException{}}}.
This happens because the collection is being serialized during internal
communication via discovery SPI, but the method's contract does not explicitly
require the collection to be serializable. As a result, users may pass valid
{{Collection<String>}} implementations that are not {{{}Serializable{}}},
leading to unexpected runtime errors.
Expected behavior: the method accepts any {{Collection<String>}} and internally
handles serialization safely.
