Description

By chance, I have a schema which results in SourceGenerator trying to create a
file called Con.java. This does not work on Windows, I assume because it is too
similar to "con", as in "copy con <file>". It's OK on Unix.

The SourceGenerator just catches the exception and says "unable to create file:
Con.java".

Maybe something slightly more useful would be nice that mentions that it is a
reserved name for Windows?

Wow, that's very strange, I never knew that limitation on windows before. I
actually did a simple test and I can't create any files with the name con.*
where * could be any extension, not just .java (of course .java is the only
importance here).

We'll try to add an explaination for this in the FAQ, seems like a windows bug
to me however.

Funny enough, this is actually still the case with 1.0.4-SNAPSHOT. And I cannot find any references to this in the XML FAQ either ... .

In Windows explorer, if I try to create D:\con.txt I get the complaint "A file with the name you specified already exists. Specify a different file name." This is definitely an issue in Windows. If I try to rename a folder to "con" the attempt is totally ignored. If I try to create a file named "con.asdfklasdlfajsldkfadsf" I get the same complaint that a file already exists with that name.

Time to point this out in the FAQ, I think .. . In addition, as we introduce proper exception handling, this will be easier to spot in the future. In addition, I think the error message should make things a little bit clearer.

I've updated JNaming and SingleClassGenerator to warn about the reserved names under Windows. Currently the code will warn only. With this update, the need to update documentation is less strong.

Change commited without a new CTF test case. The test case will require a new feature to the CTF. Also, for now the code warns under all OSes and fails under none. We might want to change this. If so, we can create another subissue of this issue.

Since we are doing work on the name clash infrastructure right now, actually, the final decision on what to do with this warning can be decided there.
