  • JDK 15 is not very relevant here. Class hierarchy padding trick was discovered a long time ago, it was only slightly modified for JDK 15 by padding with smaller data types. Myself, I discovered it back in 2013 when I was doing `@Contended` work, reading Hotspot field layouter code, and doing initial JOL work.

  • Disruptor

    High Performance Inter-Thread Messaging Library

  • This is exactly what I was curious about. I remember watching lots of (very well-made) libraries adjust for JDK 15 (e.g. JCTools, Agrona, Disruptor) and then you're just here casually writing about it in 2014.

  • WorkOS

    The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
