Summary: NullPointerException in PPrint.printText

Initial Comment:
Tidy creates a TextNode without any content if there is an inline element starting with whitespace after another element (block or inline)
Example:
<div>foo</div><span> bar</span>
Tidy creates:
[Node type=StartTag,element=div,content=
    [Node type=TextNode,element=null,text="foo",content=null]
],
[Node type=TextNode,element=null,text=null,content=null],
    [Node type=StartTag,element=span,content=
        [Node type=TextNode,element=null,text="bar",content=null]
    ]
]

In Method PPrint.printText node.textarray is null and c = (textarray[i]) & 0xFF; raises a NullPointerException

I added following workaround to PPrint.printTree:
if (node.type == Node.TEXT_NODE || (node.type == Node.CDATA_TAG && lexer.configuration.escapeCdata))
{
    if(null==node.textarray)return;    //WORKAROUND
    printText(fout, mode, indent, node.textarray, node.start, node.end);
}
