gnodet opened a new pull request, #25244: URL: https://github.com/apache/camel/pull/25244
## Summary - Replace `synchronized` blocks and methods with `ReentrantLock` in telemetry and metrics components to improve virtual thread compatibility (part of CAMEL-20199). - Converts 6 files across 3 modules: `camel-opentelemetry-metrics`, `camel-opentelemetry2`, and `camel-telemetry-dev`. - The `synchronized` keyword pins virtual threads to platform threads; `ReentrantLock` allows the virtual thread to unmount during contention, improving scalability. ### Files changed | File | Change | |------|--------| | `CounterProducer.java` | `Object lock` -> `ReentrantLock`, `synchronized(lock)` -> lock/try/finally | | `DistributionSummaryProducer.java` | Same pattern | | `TimerProducer.java` | Same pattern | | `OpenTelemetryRoutePolicyFactory.java` | Remove `synchronized` method keyword, add `ReentrantLock` field, wrap body in lock/try/finally | | `DevSpanExporter.java` | Replace 4 `synchronized(traces)` blocks with `ReentrantLock` | | `InMemoryCollector.java` | Replace 2 `synchronized` methods with `ReentrantLock` | ## Test plan - [x] `mvn test` passes in `camel-opentelemetry-metrics` (89 tests) - [x] `mvn test` passes in `camel-opentelemetry2` (37 tests) - [x] `mvn test` passes in `camel-telemetry-dev` (13 tests) - [x] Code formatted with `mvn formatter:format impsort:sort` _Claude Code on behalf of gnodet_ 🤖 Generated with [Claude Code](https://claude.com/claude-code) -- This is an automated message from the Apache Git Service.
