Confusing error message when trying to attach remote debugger to OS app run in debug mode ----------------------------------------------------------------------------------------- Key: JBIDE-22075 URL: https://issues.jboss.org/browse/JBIDE-22075 Project: Tools (JBoss Tools) Issue Type: Enhancement Components: openshift Affects Versions: 4.3.1.CR1 Reporter: Marián Labuda Assignee: Andre Dietisheim Priority: Minor Labels: debugging, openshift_v3 Fix For: 4.5.0.AM1 Attachments: debug-button-toolbar.png, error-in-launching-remote-debugger.png, error-launching-remote-debugger.png, launch-debug-no-error.mov, remote-debugger-already-launched.png If you restart the server adapter in debug mode ("Restart in Debug" in the context menu to your server adapter) the remote debugger is launched automatically. If you're not aware of this and try to launch the remote debugger entry (that was created automatically), you will face an error telling you that it cannot connect (since there's already an instance sitting on the ports). It's not obvious to the dummy user, we should improve this error-message When I am trying to run remote debugging of an application on OpenShift I get following error !!error-in-launching-remote-debugger.png! ! {code} Failed to connect to remote VM com.sun.jdi.connect.spi.ClosedConnectionException at org.eclipse.jdi.internal.connect.SocketTransportService.readHandshake(SocketTransportService.java:222) at org.eclipse.jdi.internal.connect.SocketTransportService.access$7(SocketTransportService.java:214) at org.eclipse.jdi.internal.connect.SocketTransportService$3.run(SocketTransportService.java:185) at java.lang.Thread.run(Thread.java:745) {code} *Steps to reproduce:* ASSERT: Have an OpenShift 3 application based on eap 6 template with server adapter and project in workspace. EXEC: Select "Restart in Debug" in context menu of server adapter. ASSERT: Server adapter is in state debugging ("[Debugging, Started]"). EXEC: Click on Debug Remote debugger to 'server adapter name' workbench tool item to start debugging. RESULT: Error is shown. EXPECTED RESULT: The error message should tell you that there already is an instance running.
