Janne,
OK, I've pretty much confirmed that this (pretty serious) problem is
caused by a bug in or around JSPWikiMarkupParser - apparently in the
'paragraphify' method. (Maybe not checking for nulls?) This is where
the stacktrace indicates the problem is coming from (partial copy
attached). Looking at Changelog, I note that there was a change made in
2.5.14 dealing with this. I changed to 2.5.11 and was able to generate
a new refmgr.ser quite easily (and fast - it looks like it only took a
few seconds). I then went back to 2.5.19 and used that new refmgr.ser
to run, and it was just fine.

In my application, I'm setting some WikiPage attributes, and I want
my application to control which attributes get persisted (via a
database) and which don't. So, as I mentioned above, I deleted
refmgr.ser, assuming that JSPWiki would generate a new one. But, as
I mentioned, it didn't and refused to start until I put the old one
back.
Yes, it should absolutely start (otherwise you wouldn't be able to
install it). However, if refmgr.ser is deleted, it may take a *very
long time* to boot, since jspwiki will essentially go through every
single page and parse it.
Also, if you're *relying* on some particular information being found
on wikipages, and your code happens to access it before all of the
pages have been parsed, you may experience some unwanted side effects.
