Bug # 5036554 unmarshal error on CORBA alias type in CORBA any

Platform : ALL 

Testcase directory :  <.../corba>

Test Procedure : <STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Step 1: create a file bug.idl with the following content:

// IDL file bug.idl
module bug {
    typedef string myString;
};

Step 2: Translate bug.idl with the command: idlj bug.idl
This will create the file bug/myStringHelper.java

Step 3:
Create the file JavaBug.java in directory bug with the following content:

// Java file JavaBug.java
package bug;

public class JavaBug {
    public static void main(String[] args) {
        try {
            org.omg.CORBA.ORB orb = org.omg.CORBA.ORB.init(args, null);
            org.omg.CORBA.Any any = orb.create_any();
            myStringHelper.insert(any, "hello");
            System.out.println("Any: " + myStringHelper.extract(any));
        } catch( Exception e ) {
            e.printStackTrace();
        }
    }
}  

Step 4:
Compile all java files with the command: javac -d . bug\*.java

Step 5:
Execute the program with the command: java -cp . bug/JavaBug

Step 6: Note the null pointer exception in the the output!
