The problem

The toString method on a Stream will print its identity, such as java.util.stream.ReferencePipeline$Head@6d06d69c. This is rarely what was intended.

Suppression

Suppress false positives by adding the suppression annotation @SuppressWarnings("StreamToString") to the enclosing element.
