[jetty-users] JSP Compilation error

["Ike Ikonne" <iikonne@xxxxxxxxxx>]

Hi all,


I am getting the
following stacktrace from my embedded Jetty-9.4.9. I have googled this
issue and it 
seems that some
people have ran into the same situation, but I could not find a full resolution
for 
it.

Does anyone knows
what I need to do in order to overcome this, I have been trying to upgrade
to jetty-9.4.9,
but having a hard time at it, any help will be much appreciated.

Thanks,

Ike
