Turkish locale breaks uppercase

Code reviewCode quality & reviewAlgorithms & data structuresSenior–Staff~18 min

Review this Java request router that dispatches on an uppercased command keyword.

The service runs in pods whose locale is inherited from the host. QA in the US passes; a customer in Turkey reports that valid `insert`/`index` commands are rejected.

What a strong answer looks like

Separate real bugs from style. Rank issues by severity, point at the root cause rather than the symptom, and suggest a concrete fix, specific and kind.
