I decided to try and do a standalone version along with my OS/X default FileSystemProvider project.

Just finished throwing something together for that. 

I based it on the JetBrains runtime since the ownership status here seems still sort of undetermined. 

If this isn’t the place to discuss this let me know. If that is the case, would you be interested at all in discussing it off-list @Maxim?

My first real test with no debugging is getting…

Exception in thread "FileSystemWatcher" Exception in thread "FileSystemWatcher" java.lang.InternalError: platform encoding not initialized
	at us.hall.trz.osx.MacOSXWatchService.CFRunLoopRun(Native Method)
	at us.hall.trz.osx.MacOSXWatchService$CFRunLoopThread.run(MacOSXWatchService.java:201)

Googling the error turns up occurrences but nothing I’m really understanding as connecting to what I’m doing.

Any thoughts on this?
