Compound Launch Config Debug Port Clash

I'm running into an issue / potential bug where my compound launch configuration tries to run multiple services with the same java debug port. This seems to be a non-deterministic issue and the launch configurations that succeed vary.

Here's a version of my launch config:

  "version": "0.2.0",
  "configurations": [
    {
      "type": "java",
      "name": "AxonServer",
      "request": "launch",
      "mainClass": "org.springframework.boot.loader.PropertiesLauncher",
      "classPaths": [
        "${workspaceFolder}/build/AxonServer/axonserver.jar"
      ],
      "console": "internalConsole",
      "cwd": "${workspaceFolder}/build/AxonServer",
    },
    {
      "type": "java",
      "name": "EurekaServer",
      "request": "launch",
      "mainClass": "com.company.project.framework.eureka.server.EurekaServerApplication",
      "projectName": "com.company.project.framework-eureka-server",
      "console": "internalConsole",
    },
    {
      "type": "java",
      "name": "Config Service",
      "request": "launch",
      "mainClass": "com.company.project.config.service.ConfigApplication",
      "projectName": "com.company.project-config-service",
      "console": "internalConsole",
    },
    {
      "type": "java",
      "name": "Framework Service",
      "request": "launch",
      "mainClass": "com.company.project.framework.FrameworkApplication",
      "projectName": "com.company.project-framework",
      "console": "internalConsole",
    },
    {
      "type": "java",
      "name": "Command Service",
      "request": "launch",
      "mainClass": "com.company.project.framework.commandservice.CommandApplication",
      "projectName": "com.company.project.framework-command-service",
      "console": "internalConsole",
    },
    {
      "type": "java",
      "name": "Query Service",
      "request": "launch",
      "mainClass": "com.company.project.framework.queryservice.QueryApplication",
      "projectName": "com.company.project.framework-query-service",
      "console": "internalConsole",
    },
    {
      "type": "java",
      "name": "Generation Service",
      "request": "launch",
      "projectName": "com.company.project.generation-generation",
      "mainClass": "org.springframework.boot.loader.launch.JarLauncher",
      "classPaths": [
        "${workspaceFolder}/build/generation.jar"
      ],
      "console": "internalConsole",
      "cwd": "${workspaceFolder}\\build",
    },
  ],
  "compounds": [
  {
    "name": "Start Microservices",
    "configurations": [
      "AxonServer",
      "EurekaServer",
      "Config Service",
      "Framework Service",
      "Command Service",
      "Query Service",
      "Generation Service",
    ],
    "stopAll": true,
  },
]

I get this error for several services on most launch attempts:

Error: Exception thrown by the agent : java.rmi.server.ExportException: Port already in use: 45559; nested exception is: 
	java.net.BindException: Address already in use: bind
jdk.internal.agent.AgentConfigurationError: java.rmi.server.ExportException: Port already in use: 45559; nested exception is:

... (trimmed)
Caused by: java.net.BindException: Address already in use: bind

When I check that port, one of my other configurations is indeed using that port. This is not a port used by the applications themselves, but presumably the java debug server port. When I stop my applications, those ports are no longer in use. I can also run the non-compound launch configs individually without issue, this is specifically a compound launch config issue.

Riproduci il problema con la VS Code compound launch configuration fornita e osserva l’allocazione della porta del Java debug-agent quando più servizi vengono avviati contemporaneamente. Confronta i compound launches con le configurazioni funzionanti singolarmente; il lavoro è completato quando tutti i servizi elencati possono essere avviati insieme senza competere per la stessa porta di debug.
