The article details a technical bug encountered in Adobe ColdFusion 2025 (Update 6) where the `serializeJson()` function fails to properly escape a `java.lang.Character` instance representing a double-quote, resulting in malformed JSON. The author demonstrates the bug with code, explains its impact on a local error logging system, and mentions filing an official bug report (CF-4230430) and implementing a workaround.
