Recompilation takes a long time to dereferencing

[lovepocky]

It seems that dereferencing models will happen every time even if yaml files have no change.
for example.
13:40:20.220 [pool-12-thread-4] DEBUG m.a.jackson.JsonReferenceProcessor - dereferencing #/definitions/ErrorModel
13:40:20.222 [pool-12-thread-4] DEBUG m.a.jackson.JsonReferenceProcessor - replacing subNode with {"required":["code","message"],"properties":{"code":{"type":"integer","format":"int32"},"message":{"type":"string"}},"x-$ref":"#/definitions/ErrorModel"}
...
Is this process necessary?
