PKCS#1 unpad: i=0, expected b[i]==2, got b[i]=3b Error: Decrypt error - padding function returned null!

What steps will reproduce the problem?
1. Step encrypt
   var rsa:RSAKey = RSAKey.generate(256, "10001");
   // same lame smoke test here.
   var txt:String = "hello";
   var src:ByteArray = Hex.toArray(Hex.fromString(txt));
   var dst:ByteArray = new ByteArray;
   var dst2:ByteArray = new ByteArray;
   rsa.encrypt(src, dst, src.length);
   var txt1:String = Hex.toString(Hex.fromArray(dst));
   trace(":::::::::::::::::::::: txt1:" + txt1);

2. Step decrypt from txt1, convert txt1 to ByteArray
   var src2:ByteArray = Hex.toArray(Hex.fromString(txt1)); 
   trace(":::::::::::::::::::::: src2:" + src2);  

   rsa.decrypt(src2, dst2, src2.length);
   var txt2:String = Hex.toString(Hex.fromArray(dst2));
   trace(":::::::::::::::::::::: txt2:" + txt2);

3. Output unwanted!!!
:::::::::::::::::::::: txt1:;ÏÐFóON_¼j’ãXƒ

:::::::::::::::::::::: src2:;ÏÐFóON_¼j’ãXƒ

I do not know how the process:
- Send keyPublic/keyPrivate ,send the encrypted string between Client/Server 
(Java). All the tests were conducted at the Client (AS3) but when working with 
Server, I do not know.
Hope to receive examples of this!!!
Thank you for advance!!!
