After 3 years of development, Project Lilliput, also known as 'Compact Object Headers' is going to ship JEP 450 in JDK24. We want to celebrate that by looking back at how we got here and talk about what Java users can expect from it. We also talk about why we are not done, yet, how all Java users are going to benefit from 'Lilliput 2' and what it takes to get there.
