Re: ClassLoader not loading recompiled classes

Try look at the super simple example attached below.

=============================================

import java.io.*;
import java.net.*;

public class DoubleDynmaic {
    private static void dynno(int n) {
       (new File("test")).mkdir();
       try {
          OutputStream os = new FileOutputStream("test/Test.java");
          PrintStream ps = new PrintStream(os);
          ps.println("public class Test {");
          ps.println(" public Test() {");
          ps.println(" System.out.println(" + n + ");");
          ps.println(" }");
          ps.println("}");
          ps.close();
          os.close();
          Runtime.getRuntime().exec("javac -d test
test/Test.java").waitFor();
          URL[] url = new URL[1];
          url[0] = new URL("file:test/");
          URLClassLoader cl = new URLClassLoader(url);
          Class.forName("Test", true, cl).newInstance();
       } catch (Exception e) {
          e.printStackTrace();
       }
    }
    public static void main(String[] args) {
       for(int i = 0; i < 10; i++) {
          dynno(i);
       }
    }

}
