With JDOM beta9, using XPath to select the elements to modify, you could try 
something like :

Filter filter = new ContentFilter(ContentFilter.TEXT | ContentFilter.ELEMENT);
XPath xp = XPath.newInstance("//P/..[text()!='']");
for (Iterator i=xp.selectNodes(doc).iterator(); i.hasNext(); )
{
    Element e = (Element)(i.next());
    List l = e.getContent(filter);
    for (int j=0, max=l.size(); j<max; j++)
    {
       Object child = l.get(j);
       if (child instanceof Text)
       {
          String text = ((Text)child).getText();
          String content = text.trim();
          if (content.length() != 0)
          {
             Element p = new Element("P");
             p.setText(content);

             int pos = text.indexOf(content);
             l.set(j, new Text(text.substring(pos + content.length())));
             l.add(j, p);
             l.add(j, new Text(text.substring(0, pos)));
          }
       }
    }
}

It will produce the following document :
<?xml version="1.0" encoding="UTF-8"?>
<abstract>
    <P>The XML 1.0 specification specifically reserves the colon character</P>
     <P>for use with XML Namespaces.</P>
    <P>No other use is compliant with XML 1.0. Therefore JDOM </P>
</abstract>
