You can also solve the problem on a per-user basis by granting the needed permission in a file called .java.policy in your home directory.

Works on both Unix and Windows systems as documented here: http://docs.oracle.com/javase/7/docs/technotes/guides/security/PolicyFiles.html

This might be useful if the system-wide policy file gets overwritten, for example when updating your JDK, or if you don't have permission to edit the system file.

This is what I have in my $HOME/.java.policy:

grant {
    permission java.net.SocketPermission "localhost:1527", "listen";
};
