      When the tracer client can communicate with the remote sampling port on Jaeger (5778), the tracer fails to parse the JSON content (see WFLY-11045 for more details).

      To reproduce, follow the blog post at https://medium.com/jaegertracing/automatic-tracing-of-java-ee-applications-with-wildfly-14-and-jaeger-176366927212 , starting Jaeger with:

      docker run --rm --name jaeger -p6831:6831/udp -p16686:16686 -p 5778:5778 jaegertracing/all-in-one:1.6

      And the application server with:

      JAEGER_REPORTER_LOG_SPANS=true JAEGER_SAMPLER_TYPE=remote $WILDFLY_HOME/bin/standalone.sh

      Results in:
