> JAccessWalker was not able to show component tree correctly if we switch pages for HTML content.
>
> Observation:
> The issue observed is that the children are not reported correct for root element when switching of pages happened. The reason behind it is that the `getAccessibleChildrenCount` API is called on the old `accessibleContext` object which return the children count as 0. Whenever we switch the page the children count is recalculated based on the root element but the `accessibleContext `object used to retrieve the child remains unchanged and due to that it return the children count 0.
>
> Solution:
>
> Added a condition check to create a new `accessibleContext `object to find out the children count correctly whenever we switch the pages in JEditorPane.
>
> Checked with the SwingSet2 JEditorPane demo and it reports well the component tree in JAccessWalker.
>
> Steps to verify:
>
> JBS contains the steps to reproduce the scenario.
