Java Annotated Monthly – July 2018
This month’s annotated monthly has a nice wide selection of reading for you to take to the beach, including chunky sections on Community and Culture, since it’s not always about lines of code. Or, if you actually are going on vacation, you could just leave all this alone for a while and recharge your batteries. I suggest the latter, although that’s a more difficult proposition if you have kids. You might already be looking forward to going back to work…
Covering some collections tutorials, some information about working with databases, and some more general news about Java.
- Java’s Magic Sauce – an analysis of sun.misc.Unsafe, what it is and why it’s used

- Spring REST Docs – Test driven documentation of your REST API – usually the Spring stuff lives in its own section but this month there’s not much else to put it with

- Zip Slip Directory Traversal Vulnerability Impacts Multiple Java Projects – security is important, mmmkay?
With the shorter, faster releases it’s not so clear which version number certain features will come in, but we can still keep an eye on upcoming features.

- Java Community Aims to Quantify Java 9 Adoption – to try to prevent a Java 8/9 split in the community, we’re trying to figure out who’s using Java 9 (please fill in the survey), which libraries have adopted the new module system, which work with Java 9, and which might be falling behind. The goal is to help out popular libraries that might be need resources to move forward
- Oracle has a new Java SE Subscription – if you’re using Java for commercial reasons you (or your management) should understand the New Support Pricing Structure for Java.
