Commit 1185985 has broken test?

[Andrea Del Bene]

Hi,

it seems that the commit in object has broken test 
SecurePackageResourceGuardTest.fileOnly, assertion 
'guard.acceptAbsolutePath("../test.gif")'
With this commit in ResourceSettings the default value for 
parentFolderPlaceholder has been setted to '::' but this makes always 
pass the if condition:


// Only if a placeholder, e.g. $up$ is defined, access to parent 
directories is allowed
        if 
(Strings.isEmpty(Application.get().getResourceSettings().getParentFolderPlaceholder()))
        {
            if (path.contains(".."))
            {
                log.warn("Access to parent directories via '..' is by 
default disabled for shared resources: " +
                    path);
                return false;
            }
        }


inside PackageResourceGuard.
