Worked on the Unleash/unleash-client-java repository to enhance the reliability of client configuration by introducing URI validation during initialization. Addressed a critical bug by implementing a unit test in Java that ensures an IllegalStateException is thrown if the Unleash URI is missing, thereby preventing the client from starting with an invalid configuration. Focused on improving deployment safety and reducing runtime misconfigurations, the solution leveraged Java and unit testing best practices to enforce stricter configuration correctness. This targeted update increased the robustness of the client’s setup process, ensuring that only valid configurations proceed to runtime and supporting safer production deployments.
