Apache HTTP Client generates warning on older version usage

After upgrading AWS SDK Java v2 to 2.7.13 (latest available release), I can see the following warning message:

11:04:07.122 WARN [main]: s.a.a.h.a.i.utils.ApacheUtils: NoSuchMethodError was thrown when disabling normalizeUri. This indicates you are using an old version (< 4.5.8) of Apache http client. It is recommended to use http client version >= 4.5.9 to avoid the breaking change introduced in apache client 4.5.7 and the latency in exception handling. See https://github.com/aws/aws-sdk-java/issues/1919 for more information

Apache HTTP Client has been downgraded to 4.5.7 after upgrading to the latest SDK version.

See #1168

According to Maven Dependency plugin this version of Apache HTTP Client is a transitive dependency from: software.amazon.awssdk:dynamodb:jar:2.7.13:compile

If you are facing this warning and running a project using spark-submit, a probable cause for it is Apache Spark (2.4 in my case) is using http-client of 4.5.6 and that class get picked up first by the class loader and ignores 4.5.9 used by aws-sdk-java-v2.

To solve this, we simply shade this dependency in sbt-assembly to ensure that AWS SDK used 4.5.9 instead of 4.5.6:

assemblyShadeRules in assembly := Seq(
  ShadeRule.rename("org.apache.http.**" -> "org.apache.httpShaded@1").inAll
)

Is WARN in the SDK just a warning, or an Error in fact (it causes the program not to run correctly)?
