Failed to close files in eclipse

Question

I recently upgraded my eclipse to Mars, and the .java files that were open in my previous version are pinned, and I cannot close. In the image, the first three .java files: CORSFilter.java, EmailController.java, EmailServiceImpl.java get stuck or pinned. I do not see the "x" closing when I hover over a tab. I tried opening other files, such as Assignment6.java, and tried to close everything, but they were still stuck.

This leads to chaos for being there, but he is a little worried about viewing these windows when working on a completely different project.

Thanks in advance.

Answer 1

Closing and reopening the project in the project explorer (and then opening the files) solved it for me.

Answer 2

Have you completed the eclipse for the last time? Probably the recommended file in eclipse I recommended to you 1. Install it. 2. right-click and try to kill the tab. but x on the tab no longer works and hidden errors / error may occur due to eclipse corruption
