[jdom-interest] Problem with 'setChildren' on JDOM B8

[duncan.loveday at bt.com]

Has anyone come across a problem with 'setChildren()' not clearing textual
content on JDOM B8 ?

In our application we needed a way of preserving Element content whilst
clearing textual content. We used the following line of code :-

	element.setChildren(element.getChildren());

on JDOM B7 and it worked. According to the java docs, setChildren() should
clear existing Element and non-Element content.

However, on JDOM B8 it appears to leave the text content as is. In my test,
the element has only a single item of text content and no Element content,
so I'm actually passing an empty list to element.setChildren(). After the
call I still have the one text content item there.

Is this a bug for a feature ?
