Sebastian Nagel commented on NUTCH-2596:
----------------------------------------
Hi [~balaShashanka], yes, of course, that'd be great! This is the single one
issue which should definitely get addressed for 1.17 - simple because it's time
to fully support Java 9 and upwards. One warning: I've started already two
trials to get it solved early this year. The first one by upgrading Jetty (see
[branch
NUTCH-2596-upgrade-jetty|https://github.com/sebastian-nagel/nutch/tree/NUTCH-2596-upgrade-jetty]:
however, unit tests fail to compile and also the Nutch server does not start.
The second trial was to get rid of Jetty for the HTTP protocol unit tests (see
[there|https://github.com/sebastian-nagel/nutch/tree/NUTCH-2596-http-protocol-plugin-test-remove-jsp]),
works but unfinished and I lost the confidence that it's really the right
approach (a lot of changes only to avoid Jetty and JSP). I'm by no means a
Jetty expert, so I'm happy if there is one with more experience here. So, think
about it and let me know. Be sure I'll support as I can.

> The old org.mortbay.jetty libs (not maintained since 2008) are still used for
> the Nutch server and multiple unit tests. Nutch should be upgraded to the
> maintained org.eclipse.jetty libs/packages.
> The old dependency causes the unit tests of the HTTP protocol plugins to fail
> when built with Java 9 or 10 with the following error while compiling JSP
