Environment details

API: google-cloud-compute

OS type and version: MacOS Sonoma 14.2.1
Java version: 21 (temurin)
Version(s): 1.43.0

Steps to reproduce

1. Add the following maven dependency to the pom.xml in a barebones Maven project:

<dependency>
  <groupId>com.google.cloud</groupId>
  <artifactId>google-cloud-compute</artifactId>
  <version>1.43.0</version>
</dependency>

2. Try to use ImagesClient

 try (ImagesClient imagesClient = ImagesClient.create(ImagesSettings.newBuilder().build())) {
    imagesClient.get(GetImageRequest.newBuilder()
        .setProject("foo")
        .setImage("bar").build());
  }

3. Run Main in IntelliJ (no permissions are required)

Expected behaviour: The get() fails because of a lack of permissions and the program terminates.

	at com.google.api.gax.httpjson.HttpRequestRunnable.run(HttpRequestRunnable.java:118)
	... 6 more

Process finished with exit code 1

Actual behaviour: The get() fails because of a lack of permissions and the program does NOT terminate. It just hangs. (Indicated by the IntelliJ Run toolbar's STOP button still being clickable)

	at com.google.api.gax.httpjson.HttpRequestRunnable.run(HttpRequestRunnable.java:118)
	... 6 more

Code example

public class Main {
  public static void main(String[] args) throws Exception{
    testGce();
   }
   
   public static void testGce() {
    Image i = null;
    ImagesClient imagesClient = null;
    try {
      imagesClient = ImagesClient.create(ImagesSettings.newBuilder().build());
    } catch( Exception e) {
      System.out.println("Exception!");
    } finally {
      imagesClient.shutdown();
      imagesClient.shutdownNow();
      System.out.println("Is terminated: " + imagesClient.isTerminated());  // should be true
    }
  }   
 }

Any additional information below

For some context, I am developing a Spring Shell CLI tool, and one of the commands uses the GCE ImagesClient. Before, when a user ran the command successfully, the user would then be able to run another command. This was on google-cloud-compute 1.13.0. However, now when the user runs a command using the ImagesClient the command hangs, and the program ends after a 10minute idle timeout set by Spring Shell. I've been able to reproduce the issue on a barebones Maven project.

Additionally, I've tried using imagesClient.awaitTermination(10, TimeUnit.SECONDS); but this command still hangs.
Furthermore, I've used imagesClient.isTerminated() and have observed that in the previous versions, it would return true. But now it returns false.
