Race conditions about paper HOT 3 CLOSED

Every file operation is synchronized by storage instance
https://github.com/pilgr/Paper/blob/master/paperdb/src/main/java/io/paperdb/DbStoragePlainFile.java#L112
Paper has only one storage instance. So all put/get/etc operations are synchronized.
In your example the thread which get access first will save data first. And second one rewrite old data after first one is done.

Doesn't matter you use Paper or any data storage, it should be your responsibility to write correct data in correct order. Paper just controls that more than one parallel write/read operations never happened.

Do you think the issue is exist anyway? Or we can close the issue?

We can, it was just a question wondering whether Paper handled it this way or not.
