Datadog Netty 4.0 Failing Test

This repo attempts to replicate Netty40ClientTest in a external setting.

Datadog fails to produce a child netty.client.request span which should be attached by HttpClientRequestTracingHandler, or append the x-datadog-trace-id, x-datadog-parent-id headers to the HTTP request.

Reproduce

The following forks a new jvm with the datadog -javaagent attached, and runs DatadogTestApp with the javaOptions defined in build.sbt.

sbt run
