I have one java class file like a text editor.

I tried following,

  1. Select the respective java class file from eclipse.
  2. Right click on the file and mouse hover on "Open with".
  3. Select java editor.

Now its works.

TLDR; open another workspace, then come back to the original workspace.

Ok this is odd, but for me, all the highlighting suddenly went away for Java files. I explored all of these ideas here, with no effect. I created a new workspace, planning to move everything to it. I realized that can be a pain to move many projects over, so I went back into the original workspace to look at some settings, and poof - the highlighting was working again.

I faced the same issue all of a sudden after a commit/update project operation.

The point is, default editor of Eclipse has changed somehow and we have to set it back to normal.

Try the below method,
1. Goto Windows -> Click Preferences
2. From the Preferences window goto General -> Editors -> Click File Associations
3. You can choose the default editor for *.java files here

Preferences Window

When I first opened Preferences, 'Text editor' was set as the default editor for .java files and then I changed it back to 'Java Editor'.

Now it works perfectly fine.

Closing the file's tab and re-opening it fixed it for me.

(I actually closed all the tabs...)

You probably have a corrupt installation or you have recently installed a corrupt plugin.

The following steps might help.

In your Install window,

  1. view your "already installed" plugins.
  2. select the "Installation History" tab.
  3. select a previous stable configuration
  4. Click the "Revert" button
