License Concern: GPL-2.0 w/ Classpath Exception

Transitive Dependency via android-retrofuture

Artifact: com.azure.android:azure-communication-calling

---

Summary

We are currently integrating:

com.azure.android:azure-communication-calling

into our Android application.

During the build process, our license compliance checks failed due to
transitive dependencies licensed under GPL-2.0 with Classpath
Exception.

The issue was detected by the AboutLibraries Gradle plugin,
configured with strict enforcement:

strictMode = StrictMode.FAIL

Our build also defines an explicit allowedLicenses list.
GPL-2.0 (including with Classpath Exception) is not included in our
organization's approved licenses.

Dependency Chain

The following transitive dependency chain was identified:

azure-communication-calling
  └── android-retrofuture
        └── android-retrostreams

Both:

• android-retrofuture
• android-retrostreams

are licensed under GPL-2.0 with Classpath Exception, which triggers
our strict license validation failure.

Questions

We would appreciate clarification on the following:

1. Is the use of android-retrofuture intentional and required?
2. Are there plans to replace this dependency with one under a more
   permissive license (e.g., Apache 2.0 or MIT)?
3. Is there official guidance from the Azure SDK team regarding usage
   of this dependency in commercial applications with strict license
   compliance requirements?
