Seata kryo序列化 Oracle DB中设定字段默认值，无法正常回滚

请教一下大家，因为使用时间作为联合主键，且实体类中时间类型字段为 LocalDateTime，序列化有问题，
调整序列化方式为kryo，出现一种异常情况。
当DB中表某列设定默认值时，无法正常回滚，无默认值时，可以正常回滚
这种问题，有解决方案吗？或者思考方向？
十分感谢！

The report only describes a rollback failure with Kryo serialization, LocalDateTime composite keys, and an Oracle column default; it names no source files or tests. Start by reproducing the difference between tables with and without a default value, then trace the serialization and rollback paths. Done means identifying a reproducible cause and adding a verified fix or regression test.
