JDK 1.3 java.security.BasicPermission.BasicPermission("") or
java.security.BasicPermission.BasicPermission("", String) throw IllegalArgumentException,
however it is not specified in the javadoc and not compatible with JDK1.2.2, where
IllegalArgumentException is not thrown. This causes some other methods, like
java.lang.System.setProperty("", String) also throw IllegalArgumentException, which is also
not specified in the javadoc for the appropriate method and not compatible with JDK 1.2.2.


A test example which demonstrates this problem.
===== test.java ========
import java.security.Permission;

public class test {

   public static void main (String argv[]) {

      String p = null;
      

      SecurityManager sm = new MySecurityManager();
      try {
          System.setSecurityManager(sm);
          System.setProperty("", "empty_name_value");
          p = System.getProperty("");
          System.out.println("Value set to: " + p);
          return;
      } catch (SecurityException se) {
          System.out.println("failed to setup test: SecurityException thrown");
          return;
      } catch (IllegalArgumentException iae) {
          System.out.println("Exception thrown: " + iae);
          iae.printStackTrace();
          return;
      }
   }
}

class MySecurityManager extends SecurityManager {
    public void checkPermission(Permission perm) {}
}
