(Post-launch)

1. W3C Traceparent Extraction Support

• Add a TraceparentContextExtractor that parses standard W3C traceparent headers, enabling OTel trace continuity for customers not using X-Ray propagation.

One approach to export No-Arg OTel Plugin Constructor -
The ADOT Java agent supports customization via SPI (Service Provider Interface) extensions. An extension JAR can implement AutoConfigurationCustomizerProvider to inject a custom IdGenerator into the agent's TracerProvider at startup - before any spans are created. This lets our deterministic ID generator run inside the agent's single provider, eliminating the two-provider conflict that prevents wrapper compatibility today. The extension would be packaged as a separate Lambda layer and referenced via OTEL_JAVAAGENT_EXTENSIONS. With this approach, users would get the same setup simplicity as the JS/Python SDKs: one layer, one wrapper env var, and the plugin uses the global TracerProvider instead of creating its own. Auto-instrumented HTTP/AWS SDK spans would appear alongside durable execution spans in a single unified trace.
