Migrating Scala services to Java 25 using compact object headers and G1 string deduplication reduced heap usage for workloads with many repetitive strings.
One of Java's longest-standing pain points is slow startup and warmup times. This is finally being addressed at the platform level in JDK 25 through enhancements tied to Project Leyden. The introduction of ahead-of-time (AOT) method profiling and improved command-line ergonomics represents meaningful progress, especially for cloud-native and microservices-based architectures where fast cold starts and elastic scaling are critical.
