It might help if the copy operation could detected symlinks and instead of copying it, rather recreated it somehow.

It is not clear how the symlinks should be recreated (use the same 
relative/absolute target path, or create link to source link?).

We also cannot always assume that symbolic links should not be followed.

The proposed patch simply tries to detect problematic recursive symbolic links
and skips them.

Comment 4 Jaroslav Havlin 2013-11-04 15:13:39 UTC

Please note that the attached patch doesn't work with Windows junctions,
Files.isSymbolicLink(pathToJunction) returns false. Symlinks created e.g. with
command "mklink" work correctly.

Reported for 7.3.x or earlier, no new info since then -> closing as worksforme, please reopen in case you see it.
