What Does This Do

This PR reworks #9435 and follows up on #10535.

We upgrade Logback from 1.2.13 to a modern version that properly supports Java 21 and Virtual Threads. The currently used Logback version is known to have issues in Virtual Thread environments (see the Logback issue for details), which leads to intermittent CI hangs on Java 21.

Motivation

Unblock CI on Java 21+ and keep it green..

Additional Notes

With Logback 1.2.13, jobs frequently hang on Java 21 in GitLab CI. A typical blocked call path looks like this:

VirtualThreadPerTaskExecutorTest 
  → TraceDecorator.wrapAsyncResultOrFinishSpan 
    → DDSpan.finish() 
      → PendingTraceBuffer$DiscardingPendingTraceBuffer.enqueue() 
        → Logger.debug()  ← BLOCKED on logback lock

The root cause is that legacy Logback is not aware of Virtual Threads. When multiple virtual threads share the same carrier thread, Logback’s internal locking can lead to deadlocks.

Since this behavior only manifests on JDK 21+, upgrading to a Logback version designed with Java 21 and Virtual Thread support is the correct long-term fix.

Why not slf4j-simple?

slf4j-simple works because it is truly simple: it has no internal locking and just writes to stdout. However:

  • ~99% of modules already use Logback
  • Switching logging implementations selectively feels hacky and inconsistent
  • slf4j-simple lacks many Logback fancy features

Using a modern Logback version keeps logging consistent across the codebase while properly supporting Virtual Threads.
