java.security.AccessControlException ...

 based on the specs of FilePermission:
~
 http://download.oracle.com/javase/6/docs/api/java/io/FilePermission.html
~
 my .java.policy file:
~
$ cat /media/sdb6/knet/knoppix/.java.policy
grant {
 permission java.io.FilePermission "${user.dir}/-", "read,write,execute,delete";
};
~
$ whoami
knoppix
~
$ ls -l /media/sda1/prjx/sw/text_synch | grep Kd
drwxr--r-- 2 knoppix knoppix 4096 Jul 29 16:34 Kd
~
 and this piece code:
~
// LklDir: ${user.dir}
  if(LklDir.isDirectory()){
   String aCanPth = LklDir.getCanonicalPath();
   FilePermission FP = new FilePermission(aCanPth, aUsrPerm);
   AccessController.checkPermission(FP);
....
  }
~
 I should not be getting java.security.AccessControlException:
~
$ java -Djava.security.debug=All -Dorg.xml.sax.driver=org.apache.xerces.parsers.SAXParser EntResolv00Test
