Affects PMD Version: 7.22.0

Rule:UselessPureMethodCall

Description:
The UselessPureMethodCall rule correctly detects useless peek() calls on java.util.stream.Stream, but completely fails to trigger on the exact same anti-pattern when used with the three primitive stream types (IntStream, LongStream, DoubleStream).
This is a clear false negative — the returned stream is discarded in all cases, yet only the reference Stream is flagged.

Code Sample demonstrating the issue:

import java.util.stream.Stream;
import java.util.stream.IntStream;
import java.util.stream.LongStream;
import java.util.stream.DoubleStream;

public class a{
    public void TP(){
        Stream.of("A","B").peek(System.out::println);           // TP: correctly reported
    }
    public void FN1(){
        IntStream.of(1,2).peek(System.out::println);            // FN: should report 
    }
    public void FN2(){
        LongStream.of(1,2).peek(System.out::println);           // FN
    }
    public void FN3(){
        DoubleStream.of(1.0,2.0).peek(System.out::println);     // FN
    }
}

Expected outcome:
PMD should report all four peek calls with the message:
"Do not call pure method peek if the result is not used."
But currently it only reports the Stream case (TP), completely missing the three primitive stream cases (FN).
