Cannot choose language-configuration.json file on MacOS

[OptimistMaximus]

The probelm I'm seeing is exactly the same as #258

I'm using latest MacOS "Tahoe 26.2"

I browse to the directory with foo.language-configuration.json and I see it there, but it is greyed out. Exactly like the screenshot in the above-linked issue 258. If there's any extra info or detail I can provide, please let me know.

I'm using latest eclipse as of today ...

Eclipse IDE for Java Developers (includes Incubating components)
Version: 2025-12 (4.38.0)
Build id: 20251204-0850
OS: Mac OS X, v.26.2, aarch64 / cocoa
Java vendor: Eclipse Adoptium
Java runtime version: 25.0.1+8-LTS
Java version: 25.0.1

EDIT: I can still specify the file by typing in the path. Seems like this is an issue strictly with the GUI file browser/selector.

Hi,
Looking at this quickly the filter in SelectLanguageConfigurationWizardPage seems wrong. It should probably be "*.language-configuration.json" or instead of "*language-configuration.json". Looking at the panel_shouldEnableURL() in the FileDialog, I am pretty sure "*language-configuration.json" would match nothing.

My guess is that Windows and Linux has their own native matching, but MacOS do not so they are the only using using the FileDialog.panel_shouldEnableURL(). I am not sure though. Either way using "*.language-configuration.json" on my Mac works. I have not tested it on Windows or Linux however.
