The following changes to the Default Policy Implementation and Policy File Syntax (http://download.java.net/java/jdk9/docs/technotes/guides/security/PolicyFiles.html) guide should be made as follows:
 
1. In the "Default Policy Implementation" section, the following sentence should be added:
 
"By default, permissions required by JDK modules are always granted."
 
2. In the "Default Policy File Locations" section, the following sentence still refers to standard extensions and should be changed from:
 
"The java.policy file installed with the JDK grants all permissions to standard extensions, allows anyone to listen on un-privileged ports, and allows any code to read certain "standard" properties that are not security-sensitive, such as the "os.name" and "file.separator" properties."
 
to:
 
"The java.policy file installed with the JDK allows anyone to listen on dynamic ports, and allows any code to read certain "standard" properties that are not security-sensitive, such as the "os.name" and "file.separator" properties."
 
3. The pathname to the system-wide java.policy file should be updated to reflect the new location: java.home/conf/security/java.security
