java/nio/file/Files/CopyAndMove.java is failing

[Bernd Eckenfels]

Hello,

Note also that there is a NTFS flag which makes it case sensitive. And this is since 1804 even on a per folder base. What’s worse is that the flag is per default set for Linux for Windows Files. And also the posix Flag for CreateFile enables this (which needs to be observed if you want to use it for delete)

Maybe it would be better to keep compare case sensitive (if you do not want to implement fe specific config) and instead make sure the reported roots are canonicalized from the filesystem?

Gruss
Bernd

Well spotted by Roger, it seems we have a long standing bug here. As
regards fixing this when we can re-purpose the existing bug or create a
new one. toLowerCase is locale sensitive, it's more likely that it
should be equalsIgnoreCase but I think needs a bit of study to ensure
that this is correct for cases such as when the root directory is a UNC
server.
