There is a typo in doc for method wrapAndCopyInto(S sink, Spliterator<P_IN> spliterator) in src/java.base/share/classes/java/util/stream/PipelineHelper.java
it should be "copyInto(wrapSink(sink), spliterator);", but it is "intoWrapped(wrapSink(sink), spliterator);", there is no method called intoWrapped.
