IllegalStateException in delete/update

Is it a good idea to throw IllegalStateException from delete and update methods when invoked on an unlocked record?
The interface doesn't mention this exception. But... ISE is an unchecked exception so it doesn't need to me mentioned.
What do you think?

I used IllegalArgumentException and IllegalStateException quite extensively in my application.

Suppose null was passed to createRecord(String[] record)
Which is better? NullPointerException or InvalidArgumentException?
I'd use InvalidArgumentException because it is more specific.

I used IllegalArgumentException for that purpose. But the Java classes (like String) uses NullPointerException: Unless otherwise noted, passing a null argument to a constructor or method in this class will cause a NullPointerException to be thrown.
 
It is sorta covered in the JavaRanch Style Guide.
