Prior to this commit, ExtendedBeanInfo would add non-indexed write
methods without consideration for the presence of indexed read/write
methods, which is invalid per the JavaBeans spec and per the behavior
of java.beans.Introspector. That is, a method with the signature
void setFoo(Foo foo)
Should never be registered as a write method if the following method
signature is also present in the class
void setFoo(int i, Foo foo)
In most cases, this oversight caused no problems, but in certain
situations where a bean actually contains such a mismatch of methods,
"type mismatch" errors were thrown when ExtendedBeanInfo attempted the
illegal addition against the underlying property descriptor.
The implementation is now more careful about checking the parameter type
of write methods -- if the property descriptor in question is an
IndexedPropertyDescriptor, i.e. has an indexed write method, then any
non-indexed write method candidate must have a single *array* parameter,
which conforms to the spec and to Introspector behavior.
Issue: SPR-8937
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.
