com.sun.jdi.VMDisconnectedException: Got IOException from Virtual Machine

Question

I am having trouble trying to get rid of this exception. I wrote a program to attach the debugger to a remote server using "com.sun.jdi.SocketAttach" as the attaching connector and once connection is made, I added a debug Target.

vm = connector.attach(map)
debugTarget = JDIDebugModel.newDebugTarget(launch, remoteVM, name, null, false, true, true)
launch.addDebugTarget()

My code is working fine but I get this exception everytime i close my eclipse workspace which has an active debug connection to the server. Looks like this:

!ENTRY org.eclipse.jdt.debug 4 125 2014-05-28 11:20:22.562
!MESSAGE Internal error logged from JDI Debug:

Upon investigating the issue, I found this exception is thrown when the client sends request to VM even after the VM is disconnected. But in my case, I did not had any applications deployed on the server and I was not debugging any application and still after closing the workspace, I get this exception.

I tried to implement DebugEventListener but not sure if am on the right track. Please advise if you know how to get over this issue.

Thanks

I was able to resolve this. I was not terminating the debug target before closing the eclipse programmatically. you can do that using the following code:

    // debugTargets is the list of targets that can be updated when ever a new debug target is created.
    for (IDebugTarget target : debugTargets) {
          try {
                target.disconnect();
                target.terminate();
            } catch (DebugException e) {
                //handle the exception
            }
     }
     debugTargets.clear();
