TypeError: Cannot read property 'toLowerCase' of undefined

When I create a new file Test.java and save it with the following content:

public class Test
{

}

I get this stack trace error popup:

TypeError: Cannot read property 'toLowerCase' of undefined

@aaroncarsonart: Thanks a lot for reporting, i will take a look why this happens.

[florianb]

Okay, it seems this happens if the Java-file is placed underneath a symbolic link. I am going to investigate further, it might be that this happens due to an issue in the atom-pathwatcher-library.

This is error seems to pop up since we're not dedicated handling symlinks, as the pathwatcher-API efforts. I am working on a patch.

[aaroncarsonart]

Yeah, that makes sense. I can verify the problem file was in a symbolic link directory. It linked to a location residing on my Dropbox, not sure if that would matter though. (that much is clear from my screenshot)

[florianb]

Thanks for verification - i guess i already have some sort of solution and currently try to figure out how hook into the promised callback chain of hell. I guess you can expect the patch until tomorrow.
