Azul Zulu Builds of OpenJDK function as true drop‑in replacements for the Oracle JDK because both originate from the same OpenJDK source. Core components such as the JVM and libraries are fully interchangeable, requiring no code changes or recompilation when switching.

This makes transitioning from Oracle JDK to Zulu straightforward while maintaining full standards compliance.
