--------------------------------------
Estimated Complexity: Novice
> [classlib][swing] j.s.text.AbstractDocument.BranchElement.get{Start, End}Offset throw ArrayIndexOutOfBoundsException rather than NPE
> ------------------------------------------------------------------------------------------------------------------------------------
>
> Key: HARMONY-2777
> URL: http://issues.apache.org/jira/browse/HARMONY-2777
> Project: Harmony
> Issue Type: Bug
> Components: Classlib
> Reporter: Alexey A. Ivanov
> Priority: Minor
>
> The spec states that getEndOffset throws NPE if the element has no children [1].
> The spec doesn't say anything about exceptions for getStartOffset() [2]. However, it also throws NPE in this case. The behavior of these methods should be similar in respect to exceptions.

> [2] http://java.sun.com/j2se/1.5.0/docs/api/javax/swing/text/AbstractDocument.BranchElement.html#getStartOffset()
> ======= Code to Reproduce =======
> import javax.swing.text.PlainDocument;
> import javax.swing.text.AbstractDocument.BranchElement;
> public class Test {
> public static void main(String[] args) {
> PlainDocument doc = new PlainDocument();
> BranchElement branch = doc.new BranchElement(null, null);
> try {
> System.err.println(branch.getStartOffset());
> } catch (Exception e) {
> System.err.println("getStartOffset:");
> e.printStackTrace();
> }
> try {
> System.err.println(branch.getEndOffset());
> } catch (Exception e) {
> System.err.println("getEndOffset:");
> e.printStackTrace();
> }
> }
> }
> ======= end of code =======
