Spring Framework 3.2 M2 Released

SpringSource Community Logo

An announcement from the SpringSource Community came yesterday, and apparently the Spring Framework 3.2 M2 has been released!  As always, it’s currently available from the SpringSource Repository and they even offer a quick tutorial on resolving any dependency issues (artifacts) via Maven that you may have if you’re not familiar with Maven yet (you really should be…)  The complete distribution zip is available as usual from the SpringSource community download site.

Highlights from 3.2 M2 include:

Chris Beams over at SpringSource Community had the following to say regarding both the 3.2 M2 Milestone as well as the upcoming 3.2-RELEASE:

“A major area of focus for 3.2 is ensuring that Spring Framework runs flawlessly on JDK7. M2 artifacts have been built, tested and published against JDK7 and we continue to test JDK6 compatibility in nightly builds as well. We encourage all Spring users on JDK7 to give M2 a spin in your development and test environments and provide as much feedback as possible prior to 3.2 GA. Thanks!

Users of @Configuration classes and Spring’s support for subclass proxies (proxy-target-class=true), please take note: it is now no longer necessary to add CGLIB as an explicit dependency to work with these features. As of 3.2 M2, we have upgraded to the new CGLIB 3.0. We repackage all net.sf.cglib classes to org.springframework.cglib and inline them directly within the spring-core JAR. This means that all @Configuration and subclass proxying functionality works out of the box in M2, and means no potential for CGLIB conflicts with other projects. Likewise, we have upgraded to the new ASM 4.0, which we continue to repackage and inline as we have done for quite some time now. Note however that we’ve eliminated the dedicated spring-asm jar in M2 in favor of including org.springframework.asm classes directly in spring-core. Both of these upgrades are good news for JDK7 users writing Spring components in dynamic JVM languages, as these new versions of CGLIB and ASM properly handle the new invokedynamic bytecode instruction introduced in JDK7.
