In my application.properties file, I have added spring.jackson.property-naming-strategy=SNAKE_CASE But Jackson is not honoring this property, and my REST response is still camelCase.

Non-terminal forEach() in a stream?
Sometimes when processing a Java stream() I find myself in need of a non-terminal forEach() to be used to trigger a side effect but without terminating processing.
