What could cause eclipse to display two "Source" menus for Java files?

Issue

In Eclipse 2023-06 and Eclipse 2023-09, the top menu displays two "Source" menus when I have a Java file opened. The first menu is what I would expect, and the second contains only one option "Format", which is also greyed-out.

This prevents me from using the shortcut alt + shift + s to open the Source menu.

First menu

Second menu

The second "Source" menu disappears when I'm editing other files, like XML or properties files.

What could be causing this?

• I tried resetting the key bindings, which didn't work.

• Using right-click > open with... > Java editor doesn't work either.

• Using right-click > open with... > Generic text editor made the first "Source" menu disappear, leaving only the second, that only contains the disabled "Format" option.

Solution

In this case, a plugin was adding the extra Source menu. The plugin was Spring Tools 4.

Thanks @howlger for helping with the troubleshooting on my side.
