What Does This Do

The java-net http client does not tolerate duplicate header names. The issue we have is that, if the host code contains some headers we are also injecting (i.e. x-datadog-trace-id but it can be anything else) that differs in case, we end up in having two keys. The Headers.of method checks for case insensitive duplicates and then throws:

java.lang.IllegalArgumentException
  at java.net.http/java.net.http.HttpHeaders.lambda$headersOf$1(Unknown Source)
  at java.base/java.util.HashMap.forEach(Unknown Source)
  at java.net.http/java.net.http.HttpHeaders.headersOf(Unknown Source)
  at java.net.http/java.net.http.HttpHeaders.of(Unknown Source)
  at java.net.http/jdk.internal.net.http.ImmutableHttpRequest.headers(Unknown Source)
  at datadog.trace.instrumentation.httpclient.JavaNetClientDecorator.getRequestHeader(JavaNetClientDecorator.java:51)

This results in breaking the distributed tracing.

The PR uses a TreeMap with case insensitive ordering to guarantee that there won't be case-insensitive duplicates
