If no value is stored in the current ExtensionContext

for a value with the same key

used
to create this store.
For greater type safety, consider using ExtensionContext.Store.get(Object, Class)
instead.

a new value will be computed by the defaultCreator
(given
the key
as input), stored, and returned.
