Alternatively you can simply do:
             PrivilegedExceptionAction<Path> pea = () -> 
tempPath.toRealPath();
             return AccessController.doPrivileged(pea);

In this case, limited doPrivileged does not make whole lot of difference 
jdk.zip explicitly grants for limited permissions and this doPrivileged 
block is one single operation, toRealPath.

The new test has a couple of blank lines (line 64 an 83). Formatting 
nit: indentation in line 74.
