Serialization of UUID to string in Jackson Avro > 2.11.0
问题
我有一个具有UUID属性的对象，我想将其序列化为Avro模式中的字符串。Jackson 2.11引入了修复，以更有效地序列化UUIDs，自那以后我一直在收到以下错误：
Caused by: java.lang.ClassCastException: class [B cannot be cast to class java.lang.CharSequence ([B and java.lang.CharSequence are in module java.base of loader 'bootstrap')

有没有办法切换回以前的行为？我们不想改变Avro模式，只是为了升级Jackson。
英文:
I have object with UUID property and I want to serialize it to String in Avro schema. Jackson 2.11 introduced fix to serialize UUIDs more effectively and since then I am getting

Is there any way to switch to previous behavior? We do not want to change Avro schema just to be able to upgrade Jackson.
