CaseInsensitiveDictionary (Hibernate Javadocs)

java.lang.Object
- org.hibernate.internal.util.collections.CaseInsensitiveDictionary<V>

Type Parameters:

V - the type for the stored values.
```
@Internal
public final class CaseInsensitiveDictionary<V>
extends Object
```
Wraps a ConcurrentHashMap having all keys as Strings and ensures all keys are lowercased. It does assume keys and arguments are never null, preferring to throw a NPE over adding unnecessary checks. The public exposed methods are similar to the ones on Map, but not all Map methods are exposed - only a selection we actually need; this implies it doesn't implement Map; nothing stops us to make it implement Map but at time of writing it seems unnecessary for our purposes.
