Java Logging And Exceptions

Logging

Do not hide domain-relevant logging in helper methods such as getXOrWarn(...).

Log where the problem is detected so the log points to the real origin.

Log Safety Review

Before finalizing logging changes:

• Keep log calls where the failure or skip decision is made.
• Extract collaborators only for formatting, encoding, mapping, or classification, not to hide domain-relevant logging.
• Treat external data, exception values, validation paths, and rejected values as unsafe before logging.
• Encode unsafe log values at the last formatting boundary before they are passed to the logger.
• Name extracted log-formatting methods with verb phrases such as format..., encode..., or create....
