The Dark Side of Java 8 - Lessons Learned

Conference

...aka "A Bunch of Small Reasons to Migrate Beyond JDK8"

Java 8 was one of the most important Java releases ever... but still wasn’t free of bugs, or just places where things could’ve been done better. In this session, we’ll go through a quick post-mortem session and explore various bugs, flaws and design inconsistencies along with ways how we can address those problems (if possible).

To enumerate a few, we’ll see how Stream#flatmap is broken, why Parallel Streams are not a good choice for production, or how to avoid checked exceptions boilerplate in lambda expressions by tricking the compiler.
