Walkthrough

A Makefile modification updates the Java client build process to use the build-client-streamed target instead of build-client, changing the selected build variant without altering other build steps or parameters.

Cohort / File(s)	Summary
Java client build target change Makefile	Modified Java client build invocation to use streamed variant by replacing build-client target with build-client-streamed

Estimated code review effort

🎯 1 (Trivial) | ⏱️ ~2–3 minutes

• Single-line modification with direct string replacement of make target
• Verify that build-client-streamed target exists and produces expected output format for Java client builds

Check name	Status	Explanation
Title Check	✅ Passed	The pull request title "feat(java-sdk): Makefile changes for streamed list objects generate" is clearly related to the changeset. It identifies the primary change as Makefile modifications for supporting streamed list objects in the Java SDK, which aligns with both the raw summary (switching to the streamed build variant) and the PR objectives (enabling support for streamed list objects). While the word "generate" could be slightly more explicit about what is being generated (the API layer), the title is sufficiently clear when taken in context—a teammate scanning history would understand this enables streamed list objects functionality in the Java SDK through Makefile changes.
Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.

Pull Request Overview

This pull request enables streaming endpoint support in the Java SDK by switching from the standard build target to the streamed variant. This aligns Java with Python, which already uses the streamed build process.

• Changes the Java SDK build process to include streaming endpoints from the OpenFGA API
• Specifically adds support for /streamed-list-objects endpoint that was previously excluded
