Upgrade framework codebase to JDK 8+ [SPR-13188]

[spring-projects-issues]

Juergen Hoeller opened SPR-13188 and commented

Avoiding defensive checks for java.util.Optional etc, selective use of lambdas and method references in particular with the Stream API, Java 8's reflection facilities... but also Java 7 source code refinements such as inferred generic types and multi-catch clauses.

Marking this as resolved after several passes of going through the codebase.
Obviously there'll be follow-up refinements but the initial sweep is complete.
