-------------------------------------------
I uploaded a reproducer. Just type {{./gradlew bootRun}} and observe the error. The code is totally rubbish, I just took a snapshot of my dev project.

> {{RemoteCacheImpl}} contains reference to {{org.infinispan.query.dsl.Query}}, which is not always present on the classpath (it is an optional dependency). This prevents users from obtaining {{RemteCache}} by creating a bean:
> {code}
> @Bean
> public RemoteCache defaultCache(RemoteCacheManager remoteCacheManager) {
> return remoteCacheManager.getCache();
> }
> {code}
> In such a use case, Spring treats {{RemoteCache}} as its own bean and introspects it (scans all methods and fields and checks whether there are injection points or not). Once it hits {{Query}} it generates an exception:
> {code}
> org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'defaultCache' defined in class path resource [hello/ApplicationConfiguration.class]: Post-processing of merged bean definition failed; nested exception is java.lang.IllegalStateException: Failed to introspect Class [org.infinispan.client.hotrod.impl.RemoteCacheImpl] from ClassLoader [jdk.internal.loader.ClassLoaders$AppClassLoader at ba8a1dc]
