Select All button does not select all features when multiple categories contain subcategories with the same label

[aymane-harmaz]

When using the Eclipse IDE, to install a new software from an update site (archive / url), the Select All button does not select all features if multiple categories contain subcategories with the same label.

Steps to reproduce :

• In Eclipse IDE, open Help → Install New Software…
• Click Add… and use the Archive… button to add an update site archive.
• Choose the problematic archive (where multiple categories have subcategories with the same label).
• Do not expand any category in the available software tree.
• Click the Select All button.
• Expand all categories and their subcategories
• Notice that features under Mission Control (Experimental) -> Console and Mission Control (Experimental) -> Flight Recorder were not selected and that only subcategories with the same labels in the first root category (Mission Control) have been selected

Repeat the the same steps with the archive where subcategories are having different labels and notice that all features get selected.

Could you please provide more information about the OS and Eclipse version? I tested this on macOS (26.3) and Windows 11 with the latest Eclipse version, but unfortunately the reported problem works fine in my setup.
