Steps to reproduce: 1. Install "Maven Integration for Eclipse (Juno and newer) 1.4" or "Code Recommenders" from the marketplace. 2. Restart 3. Close welcome screen Some, but not all shortcuts no longer work in the Java Editor. This includes CMD+1 (Quick+Fix)and CMD+D (Delete Line) on Mac, and CTRL+Arrow-key on Linux. After restarting Eclipse the shortcuts work again. I assume this occurs when installing a plugin that adds itself to the welcome screen. I've also reproduced this installing the Memory Analyzer plugin from its update site. Manually opening the welcome screen doesn't result in this behavior. Installing plugins that do not add itself to the welcome screen does not result in this behavior. We have encountered this before in Bug 422642 and Bug 426550.

I have just encountered the bug when installing Code Recommenders on Neon. Restart of the workbench solves the problem.
I had the same issue with the latest Eclipse Oxygen 4.7.1a. To generate the issue: 1. Open a new workspace (I tested it by letting Eclipse ask about the workspace every time) 2. Open a Java file and leave the editor open (I tested it using editor open for only one Java file - Workspace has only one Java project, not maven-based, which has only one Java file). 3. Close Eclipse 4. Reopen the same workspace (I tested it by letting Eclipse ask about the workspace every time) To work around the issue; I did the following: 1. Close the Welcome view. 2. Close open editors. 3. Open the editors again without issues 4. If wanted, can open the Welcome view again which will not cause any trouble. I was able to, constantly, regenerate the issue according to the previous scenario and work around the issue according to the mentioned steps. Environment used: * Eclipse Oxygen 4.7.1a (if it matters, Java EE bundle version 4.7.1 that has been updated to 4.7.1a) * Windows 7 - 64-Bit * Oracle JRE 9 (build 9+181) * If it matters, Java project is using JRE 1.8.0_144 (not JRE 9)
Thanks for the workaround. I also had this issue now and it is simply not possible to work with it.
@Andreas: should we move this bug to CodeRecommenders bucket?

Problem persists with Eclipse-2019-09

Been doing some testing, and it seems that the shortcuts are only broken for the active Java editor. For the text editor the shortcuts remain working, also for the non-active Java editors it works. The 'active' editor never gets the key bindings back. The workaround is to close the editor and reopen.
The same problem can be reproduced by minimizing the editor area: 1. Open a Java editor 2. Minimize the editor area 3. Restart The key bindings for 'org.eclipse.ui.textEditorScope' seem not to be active. The problem is not limited to Java editors, PDE editors suffer the same issue. At least some of the binding tables are not activated.
The area is minimized, when the welcome screen is open when eclipse is started. When the Area is minimized, it is not visible, therefore it is bound to the limbo shell. This causes that the editor is constructed under the limbo shell, as a result, the key bindings are only active in the limbo shell and not in the workbench.
