Fix tests related to java.beans.BeanInfo changes in JDK8-b117 [SPR-11139]

[spring-projects-issues]

Brian Clozel opened SPR-11139 and commented

Starting JDK8-b117, several tests fail in spring-beans.

org.springframework.beans.ExtendedBeanInfoTests > indexedReadMethodReturnsSupertypeOfIndexedWriteMethodParameter FAILED
    java.beans.IntrospectionException at ExtendedBeanInfoTests.java:340

org.springframework.beans.ExtendedBeanInfoTests > readMethodReturnsSupertypeOfWriteMethodParameter FAILED
    java.beans.IntrospectionException at ExtendedBeanInfoTests.java:323

Because of changes/fixes in the java.beans introspection codebase, some edge cases of java.beans.BeanInfo are now fixed.

Turns out that there were issues in ExtendedBeanInfo itself as well as in ExtendedBeanInfoTests.

I've rephrased those two tests to expect equivalence between standard BeanInfo and ExtendedBeanInfo there, so if they're running on a recent JDK build, the tests are going to insist on the write methods being discovered in both cases now.

As for ExtendedBeanInfo itself, I've relaxed the checks between read and write methods a bit, accepting superclass/subclass relationships in both directions there.

I intend to backport these changes to 3.2.6 as well, so that the behavior with 3.2.6 running on JDK 8 is equivalent.
