maybe I misunderstood

> so far I've been able to produce an infinite-loop or stack/heap space problem

The linked issue was resolved 5 years ago

Haha I bet it was! "Java great" according to Java.

Anyway, it's a been a while, so, I downloaded the latest Adoptium - that's the one you don't get sued for using right?

  ./javac --version
  javac 21.0.3

Full source code for pulling the first number out of a big stream:

  import java.util.stream.Stream;

  public class Main {
      public static void main(String[] args) {
          Stream.iterate(0, a -> a + 1)
                .flatMap(b -> Stream.iterate(b, c -> c + 1)
                                    .flatMap(d -> Stream.iterate(d, e -> e + 1)))
                .limit(1L)
                .findFirst()
                .get();
      }
  }

Run it:

  ./javac Main.java && time ./java Main

  Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
