Subject [jira] Created: (JSPWIKI-173) 0x1D in page creates NullPointerException in RenderingManager

0x1D in page creates NullPointerException in RenderingManager

                 Key: JSPWIKI-173
             Project: JSPWiki
          Issue Type: Bug
          Components: Core & storage
    Affects Versions: 2.4.104, 2.6.1
         Environment: tested on WindowsXP with version 2.4.104 as well as on
(running 2.6?)
            Reporter: Torsten Hildebrandt
            Priority: Critical

Enter something containing ascii #1D in an edit-box, and press save. An alternative way is
to add this character manually into a wiki page on disc.

If the page is about to be displayed, this creates an error-message like:

JSPWiki has detected an error

Error Message
Place where detected
    com.ecyrd.jspwiki.render.RenderingManager.getHTML(), line 254

This is makes a page containing this character undisplayable. 

I consider this bug quite severe as it allows to create some form of denial of service for
all editable pages .
