Broadcom has launched Spring Boot 3.5, with ongoing projects for Spring Framework 7.0 and Spring Boot 4.0 set for a November 2025 release. Null safety in Java is gaining attention via JEP Draft 8303099, while the JSpecify initiative provides standard annotations for static analysis. In a recent InfoQ discussion with Broadcom experts, best practices for utilizing Java AOT caching in Spring Boot deployments were explored, emphasizing the flexibility of Spring Boot and upcoming improvements such as the 'express warmup' feature associated with JEP 515.
"Spring Boot is flexible here. It provides an extract command to unpack an executable JAR, which can be used with a Class Data Sharing (CDS) or AOT cache."
"The AOT cache will soon support an 'express warmup' with JEP 515, proposed for Java 25, and the profiling data should come from an instance with realistic workload, potentially from production."
