Limit a stream by a predicate

Question

Is there a Java 8 stream operation that limits a (potentially infinite) Stream until the first element fails to match a predicate?

In Java 9 we can use

Even I was having a similar requirement -- invoke the web-service, if it fails, retry it 3 times. If it fails even after these many trials, send an email notification. After googling a lot, anyMatch() came as a saviour. My sample code as follows. In the following example, if webServiceCall method returns true in the first iteration itself, stream does not iterate further as we have called anyMatch(). I believe, this is what you are looking for.

import java.util.stream.IntStream;

import io.netty.util.internal.ThreadLocalRandom;

class TrialStreamMatch {

public static void main(String[] args) {        
    if(!IntStream.range(1,3).anyMatch(integ -> webServiceCall(integ))){
         //Code for sending email notifications
    }
}

public static boolean webServiceCall(int i){
    //For time being, I have written a code for generating boolean randomly
    //This whole piece needs to be replaced by actual web-service client code
    boolean bool = ThreadLocalRandom.current().nextBoolean();
    System.out.println("Iteration index :: "+i+" bool :: "+bool);

    //Return success status -- true or false
    return bool;
}
