Dear Spring community,
It's my pleasure to announce the first milestone towards Spring Framework 4.0, delivering a first cut of our work on several key themes:
With respect to Java SE 8, we support OpenJDK 8 build 88+ in several areas of the framework:
Note: Spring's Java 8 support is a work in progress and tracking OpenJDK 8 snapshots on their way to the JDK 8 Developer Preview date in September (see http://openjdk.java.net/projects/jdk8/). We expect to release a corresponding Spring Framework 4.0 release candidate around that time, to be presented at SpringOne (September 9-12; see http://springone2gx.com).
Along with 4.0 M1, we've released Spring Framework 3.2.3, containing fixes for recently reported issues but also coming with OpenJDK 8 runtime support. Spring Framework 3.2.x will support deployment on JDK 8 runtimes for applications compiled against JDK 7 (with -target 1.7) or earlier. Note that it won't support JDK 8's bytecode format (-target 1.8, as needed for lambdas); please upgrade to Spring Framework 4.0 for that purpose.
Enjoy your first experiences with Spring on OpenJDK 8, and let us know how it works for you!
