Spring Boot: Jdbc javax.net.ssl.SSLException: closing inbound before receiving peer's close_notify

Question

I am currently learning more about implementing JDBC and using databases in a Spring Boot webapp, and I encountered the following Stack Trace written in the bottom of the post.<

Answer 1

The warning looks like a MySQL driver bug with Java 11 and SSL enabled : https://bugs.mysql.com/bug.php?id=93590
Deactivating encryption because of a driver warning is a bad idea.

Your insertion problem looks more like a classic transaction issue though, I doubt it is related to the SSL warning.
