I think you could use final in a lot of places to make your code more performant (although marginally I reckon.).

After initializing the variable, you never change the value. You should therefore transcribe that behaviour semantically with the final keyword. It can help the JVM and thus increase the performance.

Suggested change

	public String provider;
	public final String provider;

	public Map<String, String> additionalInfo;
	public String name;
	public SecurityIdentityType type;

What's the goal of this class?
It doesn't seem to me to do anything meaningful

[olamothe]

It's just a data class. It is ultimately just serialized in JSON.
