Otel Java agent proxy config

Hi Otel community!

Much like https://github.com/open-telemetry/opentelemetry-java/issues/6204, I am trying to export from the otel java agent to an otlp endpoint through a proxy. We are unfortunately unable to use the collector in this instance so we’re looking for a way to configure proxy settings on the java agent.

I note that the feature to enable this has been added in https://github.com/open-telemetry/opentelemetry-java/pull/6270.

I’m not sure if it’s possible but - Can we configure proxy settings for the otlp exporter in the otel java agent by setting for example jvm flags or any other config?
Or at this stage is it only possible by interacting with code/writing an extension as mentioned in https://github.com/open-telemetry/opentelemetry-java/issues/6204#issuecomment-2072541892

I also note the feature request here https://github.com/open-telemetry/opentelemetry-specification/issues/4007 which would be the most ideal solution to our problem.

Thanks!

Start by reading the related issue 6204, pull request 6270, and specification request 4007 to understand the current proxy configuration support for the Java agent's OTLP exporter. The work is complete when the supported configuration path is established or a concrete implementation scope is identified, with any limitations documented.
