When doing pulumi up exception java.lang.UnsupportedOperationException is being thrown

Example

pulumi up

failed with an unhandled exception:

@mrge-slawek-mazur, could you share a small, self-contained program that reproduces the behavior?

[cnunciato]

I hit this today also I think -- this program should repro:

package myproject;

import com.pulumi.Pulumi;
import com.pulumi.awsx.lb.ApplicationLoadBalancer;
import com.pulumi.awsx.lb.ApplicationLoadBalancerArgs;
import com.pulumi.awsx.lb.inputs.ListenerArgs;

public class App {
    public static void main(String[] args) {
        Pulumi.run(ctx -> {

            var alb = new ApplicationLoadBalancer("lb", ApplicationLoadBalancerArgs.builder()
                .listener(ListenerArgs.builder()
                    .port(80)
                    .build())
                .build());

            ctx.export("endpoint", alb.loadBalancer().apply(loadBalancer -> loadBalancer.dnsName()));
        });
    }
}

Using:

<dependencies>
    <dependency>
        <groupId>com.pulumi</groupId>
        <artifactId>pulumi</artifactId>
        <version>(,1.0]</version>

Hi, any plans for when this might be fixed?

[smsmithee]

Hello, I have experienced the same issue and so far have been unable to get Pulumi to add my target group to my load balancer. I am very new to Pulumi and created a Github issue in what I now believe is the wrong place:
pulumi/pulumi-ai#66
It has Java code to reproduce this issue

[justinvp]

I tried @cnunciato's example and couldn't repro. But I'm using a more recent version of Java, from pulumi about:

Host
OS       darwin
Version  14.4.1
Arch     arm64

This project is written in java: executable='/opt/homebrew/opt/openjdk/bin/java' version='openjdk 18.0.2 2022-07-19

@cnunciato, does this still repro for you?
