* Tests the permission checks during the creation of a FileServerHandler.
*
* A FileServerHandler can only be created if a "read" FilePermission is
* granted for the root directory passed. The test consists of 3 runs:
* 1) security manager enabled and "read" FilePermission granted
* 2) security manager enabled and "read" FilePermission NOT granted
* 3) security manager NOT enabled
* 2) misses the required permissions to call many of the java.nio.file methods,
* the test works around this by reusing the test directory created in the
* previous run.
