I have the following issue:

We were previously using 1.7.30 and specifying our HTTP proxy using these environment variables:

SENTRY_HTTP_PROXY_HOST=host
SENTRY_HTTP_PROXY_PORT=port

This was working fine. After upgrading the 3.1.2, the proxy is not being set on the connection. If I set the proxy manually via hardcode, it works again. The documentation still claims that using the environment variables will work.

Steps to reproduce:

• upgrade working code from 1.7.30 to 3.1.2

Actual result:

• HTTP connections to Sentry fail because a proxy is required

Expected result:

• HTTP connections work

dup of #981 I believe.
not all the system envs are available on 3.x, still, you could set the proxy yourself.

pseudocode:

Sentry.init(options => {
  // read your own system envs (host, port)
  Proxy proxy = new Proxy(host, port);
  options.setProxy(proxy);
})

As I stated in the report, if I set the proxy manually, it works. However, Sentry should acknowledge this as a bug or fix the documentation.

oh sorry I misread that, link to the docs are here https://docs.sentry.io/platforms/java/configuration/#using-a-proxy
we should fix the docs.

[marandaneto]

this will be released in the next version, I'll keep it open because we need to work on the docs.
