Folks;
another strange exception bugging my running application recently (after
upgrading to jetty 9.2.5): Pretty often, I see large stack traces like
the one below in my log, which I _guess_ to be jetty complaining about
missing JSPs, but I can't tell which ones. Looking at the log, I see
rather well at which time in the web application this happens, but at
least looking at the web app itself, this error is not visible to the user.
I'm running an embedded jetty in a .jar application and use maven jetty
plugin to precompile JSPs. Any idea what could cause this exception? Any
place to look for more details?
TIA and all the best,
Kristian
