FileSystem doesn't handle "broken" file_exists() #16783
Description
I'm unable to clear my cache with console cache:clear because file_exists() returns a wrong value (false). So FileSystem can not execute rmdir later on because the directory is not empty (because symfony didn't delete the file because it thought it was not there)
This happens when the path+filename is 259 characters or longer. See also: http://superuser.com/a/467814
below you can see a test script demonstrating this problem
