A DESCRIPTION OF THE PROBLEM :
Files.find's stream pickup it's own result which comes from my body code which is the following:

===================LOG=====================
The filename, directory name, or volume label syntax is incorrect

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
I have 30 files each having size of less than 2 mb. if you can not recreate the bug, please increase count of file (not size of them)

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
indifinte loop of exception until it broke with the following ex:

sun.nio.fs.WindowsException
ACTUAL -
No exception

---------- BEGIN SOURCE ----------
try(Stream<Path> paths = Files.find(startPath, Integer.MAX_VALUE, (path, attributes) -> attributes.isRegularFile())) {
paths.forEach((path) -> {
System.out.println(path);
NameFormatter formatter = new NameFormatter();
String newName = formatter.formatNewName(path, prependFlag);
try {Files.move(path, path.resolveSibling(newName));}
catch(Exception ex) {ex.printStackTrace();}

});
}
catch(Exception ex) {ex.printStackTrace();
}

---------- END SOURCE ----------

FREQUENCY : always
