Fixed issue with recursive calls which can cause StackOverflowError. by AlexeyKuznetsov-DD · Pull Request #10535 · DataDog/dd-trace-java

AlexeyKuznetsov-DD · 2026-02-06T01:18:51Z

What Does This Do

Fixes an infinite recursive call that could lead to a StackOverflowError.
Reverts the logging backend from slf4j-simple back to logback.
The CI hangs were not caused by Logback itself, but by excessive error logging triggered by the recursion.

Motivation

Restore stable, green CI by fixing the actual root cause instead of masking the symptoms.

Additional Notes

We have test :dd-java-agent:instrumentation:vertx:vertx-web:vertx-web-3.4:test that would hang on CI with ~10% probability.

The initial hypothesis was that the issue was caused by using legacy Logback library. After switching to slf4j-simple, however, the test started hanging inside Gradle code while attempting to write to the console.

Given that:
CI runs Gradle in parallel, and the environment is virtualized, it’s likely there are limits around concurrent console output. This surfaced the real issue: the test was flooding the logs due to an infinite recursion during error handling.

All previous attempts effectively hid the problem instead of fixing it. This is further supported by the fact that we run ~200k tests using Logback without any hanging issues.

Technical Details

The infinite recursion happens in WrapRunnableAsNewTaskInstrumentation during Vertx server shutdown:

SingleThreadEventExecutor.execute() throws (executor shutting down)
  → Advice calls task.cancel(true)
    → DefaultPromise.notifyListeners()
      → safeExecute() → execute() 
        → throws again
          → Advice calls cancel() again
            → INFINITE LOOP

Fixed by adding guards against recursive calls.

Reverted usage of `slf4j-simple` back to `logback`, as real root-cause of hanged tests on CI was flooding error to logs.
