Regression (b86): OOM on parallel stream

[Mallwitz, Christian]

Hi,

The following throws (after a 10+ minute wait) an OOM - removing the parallel() bit produces the expected result of 200000.

Thanks
Christian

public class OOM {
    public static void main(String[] args) {
        System.out.println(
                java.util.stream.Streams.iterate(1L, n -> n + 1L)
                        .parallel()
                        .filter(l -> l % 100 == 0).limit(200_000).count());
    }
}
