Fixes: https://github.com/spring-cloud/spring-cloud-stream/issues/2882 When providing schema registry SSL truststore and keystore properties as classpath URL's under Kafka binder configuration, the transformations of them into corresponding filesystem URL's are not currenlty propagated into producerProperties and consumerProperties under binder configuration. This is ncessary for certain serializer/deserializer to work. See the related GH issue for more context on this.
