Java 8 bridge method handling can lead to false positive detection of autowired annotations [SPR-12187]

[spring-projects-issues]

Anton Ermolenko opened SPR-12187 and commented

Not actually false, but due to https://bugs.openjdk.java.net/browse/JDK-6695379 spring tries in inject dependencies into bridge methods in Java 8.

Test for annotations - http://pastebin.com/FRVmNmm1
Results - http://pastebin.com/k9zNpTh4

Due to this spring tries to inject dependencies into bridge methods.

Test app - for Spring - https://gist.github.com/DiKeert/1144549572771a1e3f36 - works great on Java 7, fails on Java 8.

As of 4.1.1, we're consistently excluding bridge methods in Spring's annotation post-processors now, not relying on bridge method resolution attempts like before.

I'm going to backport a minimal fix for the immediate problem to 4.0.8 as well.
