@MarkEWaite I removed these two tests because the base class (Cloud) now throws an IllegalArgumentException that does not allow the creation of DockerCloud. The warning log message will now never be generated.

Thanks @car-roll ! Has the base class been extended to handle upgrades on systems that already have a Docker cloud named with an empty string? If not, that seems like it will be needed in order to not break upgrades.

So the base class has not been extended to support empty string Cloud names, but support is still there as I did not touch the readResolve in DockerCloud.

Just to clarify what I meant, I believe the code that these two tests are testing (testConstructorWithEmptyName and testConstructorWithNullName) are testing the constructor itself

public DockerCloud(String name, DockerAPI dockerApi, List<DockerTemplate> templates) {

However, with this new jenkins version, we are now failing on the super(name) call, so that log message will now never be called. Test-wise, I do not think I can reproduce this scenario with the new Jenkins version.

The only time now we will have to deal with a null name constructor should be in existing cloud names, which is tested in testCopyConstructor.

@Test
public void testConstructorWithEmptyName() {
lr.record(DockerCloud.class.getName(), Level.ALL).capture(16);
DockerCloud cloud =
new DockerCloud("", new DockerAPI(new DockerServerEndpoint("uri", "credentialsId")), List.of());
Assert.assertEquals(cloud.getDisplayName(), "");
MatcherAssert.assertThat(lr.getMessages(), IsIterableContaining.hasItem(LOG_MESSAGE));
}

@Issue("JENKINS-70729") // Warn if cloud name is null
@Test
public void testConstructorWithNullName() {
lr.record(DockerCloud.class.getName(), Level.ALL).capture(16);
DockerCloud cloud =
new DockerCloud(null, new DockerAPI(new DockerServerEndpoint("uri", "credentialsId")), List.of());
Assert.assertEquals(cloud.getDisplayName(), null);
MatcherAssert.assertThat(lr.getMessages(), IsIterableContaining.hasItem(LOG_MESSAGE));
}

@Issue("JENKINS-70729") // Handle null or empty cloud name
@Test
public void testCopyConstructor() {
lr.record(DockerCloud.class.getName(), Level.ALL).capture(16);
DockerCloud cloud =
new DockerCloud(null, new DockerAPI(new DockerServerEndpoint("uri", "credentialsId")), List.of());
new DockerCloud("tmp", new DockerAPI(new DockerServerEndpoint("uri", "credentialsId")), List.of());

@MarkEWaite I kept the CopyConstructor test since it covers backwards compatibility, but I had to modify it to allow an "empty" named DockerCloud

Thanks @car-roll . That makes sense to me. Assigning directly to the name attribute is a nice technique. I would not have thought of that.

cloud.name = null;
Assert.assertEquals(cloud.getDisplayName(), null);
MatcherAssert.assertThat(lr.getMessages(), IsIterableContaining.hasItem(LOG_MESSAGE));
String newName = "docker-cloud-" + Integer.toHexString(cloud.hashCode());
DockerCloud copy = new DockerCloud(newName, cloud);
Assert.assertEquals(cloud.getDockerApi(), copy.getDockerApi());
