summary

Argues that widespread Optional misuse causes real performance and memory problems, citing the cache example where using orElse instead of orElseGet forces an unnecessary database call; warns against the isPresent + get anti-pattern and against assigning Optional to null; shows how to keep stream chains intact with Optional.stream and recommends moving off Java 8 to take advantage of jlink, the Alpine images and jpackage and the stability of Java 17 LTS for smaller, faster container builds.
