This type of error usually hints at connection issues, but an upgrade should not cause such issues.

Could you try and introduce changes gradually to pinpoint the issue? * hardcode the spring.datasource.url without using placeholders * trying with Spring Boot 2.1.11 and Greenwich SR4 * then changing the mysql.version to 8.0.19 * then changing the hibernate.version to 5.3.15.Final * then upgrading to Spring Boot 2.1.12 * then finally upgrading to Greenwich SR5

This should help us isolate changes.

• hardcode the spring.datasource.url without using placeholders - OK
• trying with Spring Boot 2.1.11 and Greenwich SR4 - OK
• then changing the mysql.version to 8.0.19 - ERROR

First two steps working but when I changed mysql.version to 8.0.19 I took same error. I think 8.0.19 is cause of problem

Comment From: akatkar

I have been working on this issue. The problem might be mysql database version. I was using 8.0.1 docker image as mysql db. I am trying to upgrade to newer version. 8.0.19 and 8.0.18 did not work. It can be NOT related to Spring boot.
