ClosedConnectionException when trying to debug certain Appsody templates in VSCode Windows

[naveenkaratekid]

Codewind version: 0.3.0 OS: Windows 10 IDE version:1.37.1

Description: Error being thrown when I attempt to debug any of the following Appsody templates:

• Springboot Default
• Microprofile
• Springboot Kotlin

Whenever I try to debug any of the templates I listed above, after a few moments, I get a popup that says

"Failed to attach to remote debuggee VM. Reason: com.jdi.spi.ClosedConnectionException

Steps to reproduce:

1. Create a project from one of the Appsody templates mentioned above
2. Once it's created, right click the project, and then select "Restart in Debug Mode"

launch.json @jagraj

        }
    ]
}

This appears to be a dup of https://github.com/eclipse/codewind/issues/239

After you see the message, run the Attach Debugger action manually.

@naveenkaratekid the documentation can be found via: https://github.com/eclipse/codewind-docs/blob/master/docs/_documentations/troubleshooting.md#appsody-with-codewind

@keithchong Once I saw the error message, I performed the workaround as you suggested.

After I restarted the project in Debug mode, I right clicked on the project, and then selected Attach Debugger, and I got a similar error message but with a different reason: Failed to attach remote debuggee VM. Reason: java.net.ConnectException: Connection refused: connect

Run the attach debugger command again. If the issue persists after a few attempts, restart the project in Debug mode a second time.

After verifying the issue in Mac and Windows, myself, @DavidG1011, and @sujeilyfonseca got the issue fixed using the workaround that was provided to us. In Windows, there is a different workaround we discovered: start by entering debug mode. Let the process finish, and expect it to fail (already documented that it will fail the first time). Wait for the restart notification on the bottom bar to fade away. Then, manually set the debugger.

Yes.
