Summary: Blocks of text disappear (syntax hilighting problem?)

Initial Comment:
I have had a problem for some time now with large blocks  
of text disappearing while I am editing. It is intermittent, not  
happening very often.  
  
Usually a line of text will be blank until a place where the  
code has a break in it. For example take the lines:  
  
DummyThread dummyThread = new DummyThread();  
dummyThread.start();  
  
when the error occurs, the screen might be painted like this:  
  
                         = new DummyThread();  
             start();  
  
This can happen over large areas, or to one line, all  
intermittently. Sometimes a reload helps, other times not. 
Scrolling the screen sometimes helps but usually not. 
  
I am using Mandrake linux 9.1 with Suns J2SDK 1.4.2 and 
JEdit 4.2preX.  This has happened for the past several 
weeks over several pre versions. 
 
I have a couple of screen shots which show the a section of  
code correctly, and then when the error is occuring, I'll send 
along the screen shot of the error so you can see it in action. 
 
This screenshot also shows a couple of blocks (in some 
remarks) that did manage to get redrawn partially, but this 
is a rare occurance, usually the redraw doesn't happen.

I just had the same sort of bug with jEdit 4.1 yesterday.
I haven't upgraded yet to 4.2 but I wondering if this bug is
corrected by now.

What I observed its that only blocks following /* have this
kind of problems. In my code it was when I indented a block
of commented lines (between /* and */) that this block
disappeared.
When I look the screenshot provided by dawktrrx I can see a
/* before the wrong lines.

I saw similar bug the other day -- text was getting chunked
properly and widths and offset calculations were ok, but it
was not being painted! and copying and pasting the same text
to a new, text mode buffer would still show the same
problem. However restarting jEdit resolved it. Very odd.

I don't believe this happened with 4.1.  I will have to
download a fresh copy of 4.1 and use it for a few days and
see if the same behavior occurs.
