Null pointer during getting docker id from fargate metadata when start up

[ravenadesk]

Description

We are using the java agent 8.14.0 in our application. We observed that the start up of the application takes 2 minutes longer than before.

As a comparison, we tested 8.12.0, 8.13.0 and the newest 8.18.0, and found that starting from 8.13.0, the DockerData.java was modified and start to use the java.net.URL class to retrieve the docker id.

Although the log detail is hidden since 8.17.0, I still located it according to 8.13.0's log that when attempting retrieve the docker id, exception occurs at InstrumentationImpl::noticeTracer. The call of URL.openStream and the underlying call of HttpURLConnection.getInputStream cannot complete.

We also observed that the agent attempted twice to obtain the docker id by different uri, and each costed around 1 minute.

.getTransactionProfileService()

Expected Behavior

The exception happend during tracing should not interfere with the woven class's(java.net.HttpURLConnection) behavior.

Steps to Reproduce

It is not easy to share, but I will provide the detailed environment description.

Your Environment

New Relic Java Agent 8.13.0/8.18.0
AWS ECS (ECS_CONTAINER_METADATA_URI_V4 avaliable)
Docker image from amazoncorretto:21.0.2-alpine3.19
springboot(3.3.0) application
I tried to connet to the ECS task right after it starts up, and found that the accessibility to metadata uri is no problem.
