BridgeMethodResolver throws exception when trying to find bridged method if method is declired in interface or it is abstract [SPR-9330]

Dmitry Kudinov opened SPR-9330 and commented

In combination of Scala Collection and Spring Security with annotations enabled BridgeMethodResolver failed to find bridged method for Scala's method "public abstract java.lang.Object scala.collection.TraversableLike.$plus$plus(scala.collection.TraversableOnce,scala.collection.generic.CanBuildFrom)"

In attachment there is Maven-based project with single test and all required dependencies configured.

Issue in BridgeMethodResolver#findGenericDeclaration(Method bridgeMethod) method:
...
Class superclass = bridgeMethod.getDeclaringClass().getSuperclass();
while (!Object.class.equals(superclass)) {
...
for method, defined in interface, call to "getDeclaringClass().getSuperclass()" returns null

Fix can be something like
while (superclass != null && !Object.class.equals(superclass)) {
