java.lang.NoClassDefFoundError with SpringBoot 3.2

Bug Report

Versions

  • Driver: 1.0.2.RELEASE
  • Database: PostgreSQL
  • Java: 17
  • OS: Amazon Linux 2

Current Behavior

After migrating my project from SpringBoot 3.1.5 to 3.2.0 (based on Reactor 2023.0) the following error appears:
Error was received while reading the incoming data. The connection will be closed. java.lang.NoClassDefFoundError: reactor/core/Exceptions
I believe this is due to r2dbc-postgresql incompatibility with Reactor 2023.0. Am I right? Are there any plans in the nearest future to bump r2dbc-postgresql to use Reactor 2023.0?

Can you attach the full stack trace showing the origin of java.lang.NoClassDefFoundError? The stack trace shows only a wrapper.

Sure. Here it is:

No, it's not. ClassNotFoundException typically start at:

You're right. But there was only one additional line in comparison to what I have sent earlier. Full stacktrace:

I'm not able to reproduce the problem. Also, when I upgrade this project to Reactor 2023.0.1, then I'm able to run the build without any issues.
