[Kotlin] Warning message about private final methods. [SPR-15820]

[spring-projects-issues]

Dariusz Bacinski opened SPR-15820 and commented

Recently in Kotlin version 1.1.2 there was a change regarding opening (making not final) Koltin classes . Now private methods are not being opened. This is actual change:

JetBrains/kotlin@5d4cefc

Unfortunately Spring is very verbose regarding printing warning into logs about final methods. Which leads to a warning about private final methods like this:

"INFO org.springframework.aop.framework.CglibAopProxy - Final method [private final ...] cannot get proxied via CGLIB: Calls to this method will NOT be routed to the target instance and might lead to NPEs against uninitialized fields in the proxy instance."

spring-framework/spring-aop/src/main/java/org/springframework/aop/framework/CglibAopProxy.java

Line 262 in 0d0b879

logger.info("Final method [" + method + "] cannot get proxied via CGLIB: " +

As discussed with Sebastien Deleuze @koltinlang Slack this should be checked only for public and protected methods.
