$id field is not being preserved

[snaum]

"$id" field in the schema is being converted to "id".
This is a side effect that is not expected and not documented.

IMO, schema.toString() should use the version to determine whether to print "id" or "$id"
Please see the below unit test to reproduce.

`

public void testPreserveID(){
final JSONObject validSchema1JSON = new JSONObject(validSchema1);
SchemaLoader loader = SchemaLoader.builder().schemaJson(validSchema1JSON).draftV7Support().build();
Schema schema = loader.load().build();

	JSONObject resultSchemaJSON = new JSONObject(schema.toString());
	JSONObject originalSchemaJSON = new JSONObject(validSchema1);

	assertEquals(originalSchemaJSON.get("$id"),resultSchemaJSON.get("id"));
}

Hello @snaum currently the in-memory Schema objects don't track the draft version based on which they were created. I will think about options to overcome this. Thank you for reporting the problem.

This is now fixed and released in version 1.12.0.
