JDeveloper issue deploying ADF to local integrated weblogic server: Unable to reserve .lok file for Integrated Weblogic Server

When you close JDeveloper unexpectedly without shutting down the integrated weblogic server properly, you make get the following error as soon as you try to deploy your project to the integrated WS again

 "Unable to reserve the .lok file for Integrated WebLogic Server (IntegratedWebLogicServer)"

Open the task manager on your console en kill the java.exe process that is running. Now retry.

If above does not help then go to C:\Users\..\AppData\Roaming\JDeveloper\system..\DefaultDomain . and delete the edit.lok file.
