Java-agent autoconfiguration fails for Jaeger

[shashanksdixit]

*Describe the bug
I am using Spring Boot Java and trying to auto configure traces, logs and metrics.

I have 3 Spring Boot services and in Docker I am simply calling

ENTRYPOINT` ["java", "-javaagent:opentelemetry-javaagent.jar", \
        "-jar", "app.jar"

Exporting metrics to Prometheus works well by simply configuring below

      OTEL_METRICS_EXPORTER: "prometheus"
      OTEL_EXPORTER_PROMETHEUS_HOST: "0.0.0.0"
      OTEL_EXPORTER_PROMETHEUS_PORT: "9464"

But when I configure Jaeger like below

      OTEL_TRACES_EXPORTER: "jaeger" #, zipkin"
      OTEL_EXPORTER_JAEGER_ENDPOINT: "http://jaeger:14250"

I get below exception

[otel.javaagent 2025-01-07 08:03:37:103 +0000] [main] INFO io.opentelemetry.javaagent.tooling.VersionLogger - opentelemetry-javaagent - version: 2.11.0

Note that I also tried using Java agent opentelemetry-javaagent-all.jar, but the result is same.

Environment
Docker, eclipse-temurin:17-jre

Is there anything missing.

If you look at the release notes, as of version 1.35.0:

The opentelemetry-exporter-jaeger and opentelemetry-exporter-jaeger-thift artifacts have stopped being published. Jaeger has native support for OTLP, and users should export to jaeger using OTLP instead.

See docs here for more info on configuring exporters
