Launch setting file
{
"type": "java",
"name": "Attach Service",
"request": "attach",
"processId" : "${command:PickJavaProcess}",
"timeout": 300000
}
Current Result
When the type is launch in Launch setting , the debugger starts but after a certain time period the debugger stops , but application is in running mode in the backend . on Debugger console I can see "ERROR: transport error 202: recv error: Connection reset by peer".
So I tried to do attach java process , Vscode is not able to attach , it shows the java process on popup , when I click on it , it throws error dialog saying "Failed to attach remote debuggee VM. Reason java.net.connectException:connection refused connect"
Expected Result
debugger should work
Additional Informations
Back 5/6months ago , I was able to do the debugging correct with the same project on vscode , then I recently updated it to debug the same project and its throwing exception now.
