Compiler 'Warning' not understood for relevance.

Writing a small GUI programme, and coming across a Warning (which I have suppressed / got rid of but ) which I don't understand :

warning: [path] bad path element "C:\EE_Q_CODE\packg": no such file or directory

I'm not referencing anything requiring resources in that non-existent folder, neither are there any jars or classes that are missing. So where is the idea coming from that this folder is required? Never seen such a phenomenon before.

As I say, I have got rid of the warning, (presently by adding an empty dir "packg" into the directory structure), but I'd very much like to know where the requirement for this is coming from. Any ideas please?

Are there any jar files in the build path?
krakatoaAuthor Commented:
No, none.

It would be interesting to see what your command line was

There are various reports about that error, including mention of it as a bug.

-Xlint:-path

Open in new window

should work to suppress the error as well

Yes, thanks.

Well the command line was simply javac, and my .java file. There's  nothing like a jar or anything else other than straight API imports anywhere near the code.

One of the most unexpected oddities I've yet come across in Java. It's usually me.

How could we reproduce the error on our machines?

I don’t really know ...
