I don't know, but did you try something like the following using
a TextFileDocumentProvider?

public void replaceText( IFile file, int offset, int length, String text )
{
    IDocumentProvider provider = new TextFileDocumentProvider();
    try 
    {
        provider.connect(file);
        IDocument document = provider.getDocument(file);
        if ( document != null )
        {
            document.replace(offset,length,text);
        }	            
    }
    catch (CoreException e)
    {
    }
    catch (BadLocationException e)
    {
    }					
}
