Hi there,

I am working with a small project where I would like to define my own CardRuntimeException, just like the CryptoException case. Using the same code as in CardException:

public class MyException extends javacard.framework.CardRuntimeException


{

private static MyException systemInstance;


// MyException reason codes


...


public MyException(short reason)


{

super(reason);


if (systemInstance == null)
systemInstance = this;

}

Every time a MyException is being thrown a JavaLangNullException are being thrown instead. By using a simulator I found out that the reason for this is that my systemInstance in MyException is NULL.

Any ideas?
