[java] CloseResource possible false positive with Primitive Streams · Issue #2402 · pmd/pmd · GitHub

Affects PMD Version: 6.22.0

Rule:

CloseResource

Description:

In Issue #1922 only java.util.Stream got handled, now the same false/positives occure on IntStream, LongStream and DoubleStream

Code Sample demonstrating the issue:

public class PmdPrimitiveStreamReproducer {

    public void reproduceIntStream() {
        IntStream iStream = IntStream.of(1).filter(i -> i < 5);
        iStream.anyMatch(i -> i < 5);
    }


    public void reproduceLongStream() {
        LongStream lStream = LongStream.of(1).filter(i -> i < 5);
        lStream.anyMatch(i -> i < 5);
    }


    public void reproduceDoubleStream() {
        DoubleStream dStream = DoubleStream.of(1).filter(i -> i < 5);
        dStream.anyMatch(i -> i < 5);
    }

}

Expected outcome: no violation should be thrown

• Does PMD report a violation, where there shouldn't be one? -> false-positive
