Java: Migration Strategy
Answer
The JVM ensures that newer Java features run on older bytecode.
Backward compatibility is a key strength of the JVM, allowing older bytecode to run on newer JVM versions. This is crucial when incrementally adopting modern Java features. For example, you can introduce Java 17 features like sealed classes into a legacy application without fear of breaking existing functionality, thanks to the JVM's compatibility guarantees.
