[ipv6] RFR: 8224256: test/jdk/java/security/SecureClassLoader/DefineClass.java hardcodes 127.0.0.1

[Daniel Fuchs]

Hi Arthur, [adding security-dev]

   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,
