File Associations don't work when file only have extension(_no filename_)

[parallels999]

Apache NetBeans version

Apache NetBeans 21

What happened

On php laravel there is .env file, without name, only extension
https://github.com/laravel/laravel/blob/58baff2c70144c7cd4c04eecb51fee5a24e873a8/composer.json#L42
After adding File Association, works on any *.env file, except for the one that has no name, only extension(main one)

Language / Project Type / NetBeans Component

PHP project

How to reproduce

Just create any file with new extension but without name, only the extension, add the File Association(I'm using text/x-apache-conf), then File Association does't work on that file

Did this work correctly in an earlier version?

No / Don't know

Operating System

This is not a bug, but works as intended (lines 232 + 239):

netbeans/platform/masterfs/src/org/netbeans/modules/masterfs/filebasedfs/utils/FileInfo.java

Lines 229 to 241 in 905ff7e

	public static final String getName(String name) {
	int i = name.lastIndexOf('.');
	/** period at first position is not considered as extension-separator */
	return (i <= 0 || i == (name.length()-1)) ? name : name.substring(0, i);
	}
	public static final String getExt(String name) {
	int i = name.lastIndexOf('.') + 1;
	/** period at first position is not considered as extension-separator */
	return ((i <= 1) || (i == name.length())) ? "" : name.substring(i); // NOI18N
	}

With my linux hat on, I agree with that assessment. Traditionally files with leading dot are hidden files. So from that perspective .env is not a file that has only an extension, but a hidden file, that has no extension.

Yes, on linux, but windows is another story, right?

In the world of DOT files inside of the projects nowadays (.eslintrc, .prettierrc, .env, .anything) we should handle them too. It is not just a linux/windows thing anymore I would say. Let this convert to a discussion to talk about the cases.
