This attaches the async call chain to the exception as a suppressed entry, with no code changes. It supports ExecutorService, CompletableFuture, ForkJoinPool, Reactor and RxJava.</p> <p>Overhead is very small: ~1 µs per CompletableFuture pipeline in the default mode.</p> <p>It doesn't replace OpenTelemetry. It works in-process, with no infrastructure needed.</p> <p>Currently it is on version v0.1.0-alpha.3, not production-hardened yet, beacuse I need sm feedback first so I know this is worth it, especially on OSGi and Kotlin coroutines.</p> <p><a href="https://github.com/AfonsoPaiva/ARIADNE" rel="noopener noreferrer">GitHub</a></p> <p>A star helps if you find it useful 🙏</p> java opensource backend
