This bug was found by St.Petersburg Java SQE team (by Alexander Kuzmin).

The java.io.FileOutputStream.write(byte[],int,int) does not work properly
with IOException.
If the file that FileOutputStream object connected to doesn't exist any more,
FileOutputStream.write(byte[],int,int) does not throw IOException.
