Prior to this change, CachedIntrospectionResults delegated to ExtendedBeanInfo by default in order to inspect JavaBean PropertyDescriptor information for bean classes. Originally introduced with SPR-8079, ExtendedBeanInfo was designed to go beyond the capabilities of the default JavaBeans Introspector in order to support non-void returning setter methods, principally to support use of builder-style APIs within Spring XML. This is a complex affair, and the non-trivial logic in ExtendedBeanInfo has led to various bugs including regressions for bean classes that do not declare non-void returning setters. This commit takes advantage of the new BeanInfoFactory mechanism introduced in SPR-9677 to take ExtendedBeanInfo out of the default code path for CachedIntrospectionResults. Now, the new ExtendedBeanInfoFactory class will be detected and instantiated (per its entry in the META-INF/spring.beanInfoFactories properties file shipped with the spring-beans jar). ExtendedBeanInfoFactory#supports is invoked for all bean classes in order to determine whether they are candidates for ExtendedBeanInfo introspection, i.e. whether they declare non-void returning setter methods. If a class does not declare any such non-standard setter methods (the 99% case), then CachedIntrospectionResults will fall back to the default JavaBeans Introspector. While efforts have been made to fix any bugs with ExtendedBeanInfo, this change means that EBI will not pose any future risk for bean classes that do not declare non-standard setter methods, and also means greater efficiency in general.

Spring Framework
The Spring Framework provides a comprehensive programming and configuration model for modern Java-based enterprise applications - on any kind of deployment platform. A key element of Spring is infrastructural support at the application level: Spring focuses on the "plumbing" of enterprise applications so that teams can focus on application-level business logic, without unnecessary ties to specific deployment environments.
The framework also serves as the foundation for Spring Integration, Spring Batch and the rest of the Spring family of projects. Browse the repositories under the SpringSource organization on GitHub for a full list.
.NET and Python variants are available as well.
Downloading artifacts
See downloading Spring artifacts for Maven repository information. Unable to use Maven or other transitive dependency management tools? See building a distribution with dependencies.
Documentation
See the current Javadoc and reference docs.
Getting support
Check out the Spring forums and the spring and spring-mvc tags on Stack Overflow. Commercial support is available too.
Issue Tracking
Report issues via the Spring Framework JIRA. Understand our issue management process by reading about the lifecycle of an issue. Think you've found a bug? Please consider submitting a reproduction project via the spring-framework-issues GitHub repository. The readme there provides simple step-by-step instructions.
Building from source
The Spring Framework uses a Gradle-based build system. In the instructions
below, ./gradlew is invoked from the root of the source tree and serves as
a cross-platform, self-contained bootstrap mechanism for the build. The only
prerequisites are Git and JDK 1.6+.
check out sources
git clone git://github.com/SpringSource/spring-framework.git
compile and test, build all jars, distribution zips and docs
./gradlew build
install all spring-* jars into your local Maven cache
./gradlew install
import sources into your IDE
Run ./import-into-eclipse.sh or read import-into-idea.md as appropriate.
... and discover more commands with ./gradlew tasks. See also the Gradle
build and release FAQ.
