// This system policy file grants a set of default permissions to all domains
// and can be configured to grant additional permissions to modules and other
// code sources. The code source URL scheme for modules linked into a
// run-time image is "jrt".
//
// For example, to grant permission to read the "foo" property to the module
// "com.greetings", the grant entry is:
//
// grant codeBase "jrt:/com.greetings" {
//     permission java.util.PropertyPermission "foo", "read";
// };
//

// default permissions granted to all domains
grant {
    // allows anyone to listen on dynamic ports
    permission java.net.SocketPermission "localhost:0", "listen";

    // "standard" properies that can be read by anyone
