The method
    public void removeEntries(int index, int length)
of class
    javax.swing.SizeSequence
does not throw IllegalArgumentException if:

    1) 'index' < 0
    2) 'index' >= getSizes().length
    3) 'length' < 0
    4) 0 <= 'index' < getSizes().length and
       0 <= 'length' < getSizes().length and
       'index'+'length' >= getSizes().length
    5) setSizes(..) has not been called before

Currently the method throws implementation related exceptions:
ArrayIndexOutOfBoundsException and NegativeArraySizeException.

The doc says:
--------------------------------------------------
public void insertEntries(int start,
                          int length,
                          int value)

      Adds a contiguous group of entries to this SizeSequence.
      Parameters:
            start - the index to be assigned to the first entry in the
                    group
            length - the number of entries in the group
            value - the size to be assigned to each new entry

The demo test:
--------------------------------------------------
import javax.swing.SizeSequence;
public class Test {
    static void test(int caseno,
                     SizeSequence ss,
                     int index,
                     int length) {
        try {
            ss.removeEntries(index,length);
        } catch (Exception e) {
            System.out.println(caseno+") "+e);
        }
    }

    public static void main(String argv[]) {
        int[] sizes = {1000, 2000, 3000};

        SizeSequence ss = new SizeSequence();
        ss.setSizes(sizes);
        test(1,ss,-1,7);

        ss = new SizeSequence();
        ss.setSizes(sizes);
        test(2,ss,ss.getSizes().length,7);

        ss = new SizeSequence();
        ss.setSizes(sizes);
        test(3,ss,1,-2);

        ss = new SizeSequence();
        ss.setSizes(sizes);
        test(4,ss,2,2);

        ss = new SizeSequence();
        test(5,ss,1,1);
    }
}

Output:
--------------------------------------------------
1) java.lang.NegativeArraySizeException
2) java.lang.NegativeArraySizeException
3) java.lang.ArrayIndexOutOfBoundsException
4) java.lang.ArrayIndexOutOfBoundsException
5) java.lang.NegativeArraySizeException
