GraalVM In OpenJDK And More JavaOne Announcements - Inside Java Newscast #36#video#community #java‑8 #java‑17 #openjdk #performance
Oracle will contribute GraalVM's just-in-time compiler and native image technology to OpenJDK. It will also create EA and GA builds for JavaFX 20+ and is hard at work at creating generational ZGC to vastly improve ZGC's already impressive performance. And then there's the Java SE Subscription Enterprise Performance Pack, a drop-in replacement for JDK 8 with JDK 17 performance.

Rebutting 5 Common Stream Tropes#post#java‑8 #rant #streams
Articles about Java 8's streams often repeat a bunch of tropes: succinctness, ugly mechanics, anemic pipelines, weak exception handling. This is a rebuttal!

Beware Of findFirst() And findAny()#post#java‑8 #streams
Stream.findFirst() and findAny() work with any number of elements in the stream. Make sure to reduce(toOnlyElement()) if there should be at most one.
