Hi Arthur,

  18 // For IPSupport
  19 grant {
20 permission java.net.SocketPermission "localhost:0", "listen,resolve"; 21 permission java.util.PropertyPermission "java.net.preferIPv4Stack", "read";
  22 };

It might be better if these permissions were granted to the
library only.

90 // Base64 encoded bytes of simple class: "package bar2; public class Bar2 {}"
  91     private final static String BAR2_CLASS =
92 "yv66vgAAADQADwoAAwAMBwANBwAOAQAGPGluaXQ+AQADKClWAQAEQ29kZQEA" +
...

Which version of javac did you use to generate the class?
I wonder if it should have the same major/minor version than
the other classes in that file. But maybe it doesn't matter.

best regards,

test/jdk/java/security/SecureClassLoader/DefineClass.java checks that a security manager works with "http://127.0.0.1";. This fails on IPv6-only systems.

This change tests 127.0.0.1 if IPv4 is available, then tests ::1 if IPv6 is available. Created a new class for testing ::1 since we can't have duplicate classes.
