String and Text Processing in Java on a Scale (Kyrylo Holodnov, Yaroslav Yermilov - Software Engineers @Grammarly)
Our Java applications handle millions of strings per second. We work with different platforms, including mobile. On a scale, even rare things happen. You can bet that eventually, an innocent text will crash your server… or the whole cluster. Over the years we have tried many performance tricks. Or should we call it premature optimizations?
In this talk, we’ll share what we have learned about heavy string processing in Java:
– Upgrading to Java 11. New java.util.String – expectations and reality
– JVM string optimizations and hacks – which ones do you need?
– Tips for fast and robust regular expressions
– Emoji that make you cry
– Services in other languages – what is the true length of my Java string?”

Starting from January 2019 Java 8 is end of life. Last public update was published and no more updates are expected. Most Java applications are using JDK 8. What they have to do? What are the available options? The most obvious option is to move towards Java 11 as new LTS version. What problems are expected? Is it possible to make this process step by step? I'll provide information about my experience of moving project on Java 11 and pitfalls behind that. If it is not an option for your project there is alternative JDKs that will provide support for Java 8 for few more years. Let's not make panic that from now Java is not free and choose the best option for project
