SimpleDateFormat

Hi,
I run the following piece of code.


-----------------------
Calendar datai;
datai = Calendar.getInstance();
datai.set(1899, 11, 30, 0, 0); // start time for delphi 
SimpleDateFormat sdf = new SimpleDateFormat();
System.out.println("datai:"+ sdf.format(datai.getTime()));
------------------------


It crash with gcj version:
gcj.exe (GCC) 4.3.0 20080305 (alpha-testing) mingw-20080502

error is:
Exception in thread "main" java.lang.ExceptionInInitializerError

There is no error with eclipse and with:
gcj.exe (GCC) 3.4.5 (mingw-vista special r3)


How we can understand if it is a gcj problem or a mingw problem?
