As the title suggests, Spring 4.2.5.RELEASE cannot inject into Java 8 default methods via xml context files.

I have thrown together a simple example on GitHub to demonstrate how this fails:

    void setSomeDate(LocalDate localDate);

    default void setSomeDateInDayMonthYear(String dayMonthYear) {
        setSomeDate(LocalDate.parse(dayMonthYear, DateTimeFormatter.ofPattern("dd/MM/yyyy")));

An egregious workaround is to reference the default method from the implementation as follows:

public void setSomeDateInDayMonthYear(String dayMonthYear) {

Affects: 4.2.5

Unfortunately, even the JDK's own JavaBeans Introspector does not detect setters and getters as default methods. I've added some explicit code to our CachedIntrospectionResults, querying the introspector explicitly for each implemented interface and adding missing bean properties that way.

This will be available in the upcoming 4.3.0.BUILD-SNAPSHOT and make it into 4.3 RC2.
