Bumps [io.opentelemetry:opentelemetry-bom-alpha](https://github.com/open-telemetry/opentelemetry-java) from 1.22.0-alpha to 1.23.0-alpha. <details> <summary>Release notes</summary> <p><em>Sourced from <a href="https://github.com/open-telemetry/opentelemetry-java/releases">io.opentelemetry:opentelemetry-bom-alpha's releases</a>.</em></p> <blockquote> <h2>Version 1.22.0</h2> <h3>API</h3> <ul> <li>WARNING: GlobalOpenTelemetry trigger of autoconfiguration is now opt-in. Previously, <code>GlobalOpenTelemetry.get</code> triggered autoconfiguration if <code>opentelemetry-sdk-extension-autoconfigure</code> was detected on the classpath. That behavior is now opt-in by setting environment variable <code>OTEL_JAVA_GLOBAL_AUTOCONFIGURE_ENABLED=true</code>. (<a href="https://github-redirect.dependabot.com/open-telemetry/opentelemetry-java/pull/5010">#5010</a>)</li> <li>Update LoggerBuilder, MeterBuilder, TracerBuilder javadoc (<a href="https://github-redirect.dependabot.com/open-telemetry/opentelemetry-java/pull/5050">#5050</a>)</li> </ul> <h4>Context</h4> <ul> <li>Make closing scope idempotent and non-operational when corresponding context is not current.

To use, configure your <code>MetricExporter</code> with a default aggregation of <code>Aggregation.base2ExponentialBucketHistogram()</code> for histogram instruments. If using OTLP exporter with autoconfigure, set <code>OTEL_EXPORTER_OTLP_METRICS_DEFAULT_HISTOGRAM_AGGREGATION=BASE2_EXPONENTIAL_BUCKET_HISTOGRAM</code>.

OpenTelemetry Java Contrib
This project is intended to provide helpful libraries and standalone OpenTelemetry-based utilities that don't fit the express scope of the OpenTelemetry Java or Java Instrumentation projects. If you need an easier way to bring observability to remote JVM-based applications and workflows that isn't easily satisfied by an SDK feature or via instrumentation, this project is hopefully for you.
Provided Libraries
- AWS Resources
- AWS X-Ray SDK Support
- AWS X-Ray Propagator
- Consistent sampling
- JFR Streaming
- JMX Metric Gatherer
- OpenTelemetry Maven Extension
- Runtime Attach
- Samplers
Getting Started
# Apply formatting
$ ./gradlew spotlessApply
# Build the complete project
$ ./gradlew build
# Run integration tests
$ ./gradlew integrationTest
# Clean artifacts
$ ./gradlew clean
Contributing
The Java Contrib project was initially formed to provide methods of easy remote JMX metric gathering and reporting, which is actively in development. If you have an idea for a similar use case in the metrics, traces, or logging domain we would be very interested in supporting it. Please open an issue to share your idea or suggestion. PRs are always welcome and greatly appreciated, but for larger functional changes a pre-coding introduction can be helpful to ensure this is the correct place and that active or conflicting efforts don't exist.
