Nested Class/Enum issue with JRockit
jrockit 1.5 R27.5
Windows XP
I'm running into class loading/cacheing issues while using jrockit with nested
classes (with ant). It works when using the Sun JVM (1.5).
Example:
Java:
package com.example;
import org.apache.tools.ant.taskdefs.SQLExec;
public class Test
{
/**
* List of databases support.
*/
public enum Database
{
DB1,
DB2,
DB3,
DatabaseNumber4
}
public static void testMethod() {
SQLExec.OnError error = new SQLExec.OnError();
}
}
Ruby:
Java::com.example.Test::Database.values()
It will first cause a null pointer:

and then on every subsequent request return error:
"Anonymous modules have no name to be referenced by"
Let me know if you need any more information
