Java Weekly, Issue 390

1. Spring and Java

>> CopyOnWriteArrayList and Collection#toArray() [javaspecialists.eu]

Deep into safe usage of the CopyOnWriteArrayList. If you haven’t been working on concurrency lately, this is a solid read.

>> What’s New in Java 16 [infoq.com]

I assume you’re not yet using Java 16 in production. A half-hour very well spent.

Also worth reading:

• >> Working with AWS DynamoDB and Spring [reflectoring.io]
• >> Quick and Seamless Release Management for Java projects with JReleaser [infoq.com]
• >> Hibernate Proxies – Why they’re used and how to unproxy them [thorben-janssen.com]

Time to upgrade:

• >> Hibernate ORM 5.5.2.Final released [in.relation.to]
• >> Hibernate Search 6.0.4.Final released [in.relation.to]

2. Technical and Musings

>> Making POST and PATCH requests idempotent [mscharhag.com]

Easy to not get this right, and definitely important to – yes, idempotency is the correct way to implement these operations but also makes things so much easier long term.

>> Software Mistakes and Tradeoffs [manning.com]

Looks like a very interesting read when it’s fully out, and Tomasz shared a 35% off code with me to include in this week’s Java Weekly: nlbaeldung21. Enjoy
