Bug Report

Hello, looking for some help here! While using Hooks.enableAutomaticContextPropagation() in a Spring Boot 3.0.2 application and reactor-core 3.5.3 and PostgreSQL R2DBC driver, UnsupportedOperationException is thrown while trying to perform any database operation using reactor-netty-client (ReactorNettyClient:811)

Versions

  • Driver: 1.0.1.RELEASE
  • Database: Postgresql 13.4
  • Java: 17
  • OS: Windows
Stack trace 
java.lang.UnsupportedOperationException: Although QueueSubscription extends Queue it is purely internal and only guarantees support for poll/clear/size/isEmpty. Instances shouldn't be used/exposed as Queue outside of Reactor operators.

Expected behavior/code

Database operation completes successfully

I have zero idea why this happens. As this is new functionality being used with the driver, I suggest filing a ticket at https://github.com/reactor/reactor-core/issues as the offending code comes from the reactor.core.publisher package.

Closing this one as that is a Reactor issue.
