OSGi support and tests for OTLP exporters by jack-berg · Pull Request #8401 · open-telemetry/opentelemetry-java

jack-berg · 2026-05-12T19:43:45Z

Related to #768, followup to #7964.

Extend OSGi support to OTLP exporters by including appropriate metadata to resolve sender SPI.

Rework :integration-tests:osgi to add a helper to create OSGi test suite bundles consisting of different combinations of dependencies. With this PR, there are test suites for:

Just the SDK
SDK + OTLP HTTP exporters + OkHttp sender
SDK + OTLP gRPC exporters + OkHttp sender
SDK + OTLP HTTP exporters + Jdk sender

I did a before an after of each impacted artifact's MODULE.MF to make it easier to review:

Starts to look good, a lot of tests. Will validate if I can update my project to use these bundles instead of my own rewrapped ones:

https://github.com/orbinson/aemaacs-opentelemetry-instrumentation
https://github.com/orbinson/adaptto-opentelemetry-demo

You had to do some manual fixes in gradle it seems, the latest BND plugin wasn't correctly detecting it?

That would be great!

Correctly detecting what? The SPI provides / requires instructions?

royteeuwen · 2026-05-14T19:22:40Z

Tested on a running AEMaaCS SDK 2026.2 (OSGi with Apache Felix).

What works

OSGi metadata is correct. Every bundle has Bundle-SymbolicName,
Bundle-Version, versioned Export-Package clauses with proper uses: and
versioned Import-Package clauses. BSN is unambiguous.
Optional resolution for vanilla SDK case is now correct in
exporter-common and exporter-otlp. io.grpc, io.grpc.stub,
com.google.common.io, com.google.common.util.concurrent,
com.fasterxml.jackson.core are all resolution:=optional — bundle resolves
without those even being present.
opentelemetry-exporter-sender-jdk is the perfect OSGi candidate. Imports are
exclusively JDK packages (java.net.http, java.io, java.util, ...). No
external transitive deps. Provides the HttpSenderProvider SPI through
osgi.serviceloader capability so SPI Fly picks it up automatically. This
one resolves and starts cleanly without any third-party bundle in the
container.

Remaining issues

Issue 1 — `sun.misc` is a mandatory `Import-Package` in `opentelemetry-exporter-common`

The manifest contains:

Import-Package: ...,sun.misc

(no resolution:=optional).

Source culprit:
exporters/common/src/main/java/io/opentelemetry/exporter/internal/marshal/UnsafeStringEncoder.java
uses sun.misc.Unsafe. There already is a fallback path
(StringEncoder / StringEncoderHolder) that picks a non-Unsafe encoder when
Unsafe is unavailable, so this dependency is runtime-optional in the Java
sense. The OSGi manifest should reflect that.

This single import cascades into 4 unresolved bundles
(exporter-common, exporter-otlp, exporter-otlp-common,
sdk-extension-autoconfigure).

Fix: add sun.misc to osgiOptionalPackages (or
osgiUnversionedOptionalPackages) for the exporters:common module.

Issue 2 — `io.opentelemetry.sdk.internal` exported by 5 bundles (was in the previous commit too)

-exportcontents: !io.opentelemetry.internal.shaded.*,io.opentelemetry.*
still catches io.opentelemetry.sdk.internal.* in sdk-common, sdk-trace,
sdk-metrics, sdk-logs, and exporter-common. Different classes live in
that package in each module — that's a split package.

In Felix this resolves to whichever provider gets picked first by the
resolver, and uses constraints further reduce flexibility. Either:

Move internal helpers to module-specific internal.* packages
(io.opentelemetry.sdk.trace.internal, io.opentelemetry.sdk.metrics.internal,
etc.) so each is owned by one bundle, or
Exclude io.opentelemetry.sdk.internal from Export-Package along with the
already-excluded io.opentelemetry.internal.shaded.*.

Issue 3 (nit) — Recommend `exporter-sender-jdk` in OSGi docs

The PR's integration tests include OtlpHttpJdkTest, which is the simplest
OSGi setup: zero non-JDK runtime deps, smallest bundle graph, no SPI Fly
quirks. Worth calling out in the OSGi guide as the default recommendation,
with okhttp as the option for users who specifically need okhttp's connection
pooling.

End-to-end verification (blocked)

I couldn't confirm an OTLP record actually reaches a collector via the native
bundles because exporter-common doesn't resolve in AEM due to Issue 1. Once
sun.misc is marked optional, I can retest both the jdk + okhttp branch easily

…s.* to avoid split package, add sun.misc as optional unversioend unversioned

Thanks @royteeuwen. Check out 95912aa:

Issue 1: you're right - I added sun.misc to the set of optional unversioned packages.
Issue 2: ah yeah we have some funky vendoring / relocation going on in :sdk:trace-shaded-deps. Adjusted to relocate to io.opentelemetry.sdk.trace.internal.shaded.jctools instead to avoid split package.
Issue 3: Yeah after the dust settles on this we'll want to add a new OSGi section to the docs, and explain things like this.
