Lots of interesting writeups on Java 9 this week.
Here we go…
1. Spring and Java
A summary of the Spring Tips series, including integrations with jOOQ, Couchbase, MyBatis, and a lot more.
Looks like that waiting for Java EE 8 finally comes to an end.
Java 8 comes with an overwhelming set of collectors for the Stream API but sometimes even this is not enough and you need to create your own collectors – which might be more complicated than you thought.
Another solid guide to modularity in Java 9.
Redhat team raised multiple issues regarding the current implementation of the Jigsaw Project. It looks like there were multiple compromises made when developing the new modular system for Java.
There are quite a few common misconceptions about Hibernate – one of which is that it can only be used for simple mapping. It turns out you can call database functions, stored procedures, map views, and quite a bit more.
GC logs can be a source of crucial information if you know how to read it – which can be tricky because GC logging is not thread-safe (prior to Java 9).

3. Musings
Discovering APIs by experimenting with them is fun but not very efficient (especially from the customer side of things). By taking care of documentation, we can get a lot more productive in the long term.

It's not a secret that measuring productivity using LoC/day is less than ideal and can be hacked easily, although it still appears quite attractive to some managers.
