Hello,

First, thank you for FESS, it’s a great software!
I’m a new user and I’m testing the latest zip (FESS 12.1.0) on Ubuntu 16.04 with IBM Java8 (bug report details at the end).
Installation seems alright as I can access the admin dashboard (1 node, 44 indices, …).

My first test is to setup a new File System crawler through the Wizard and launch it manually from the Job Scheduler as suggested in the documentation.
But it has stopped almost instantly.
From the logs, I have found this strange output:

2018-02-27 17:22:18,444 [main] ERROR Crawler does not work correctly.
org.lastaflute.di.core.factory.dixml.exception.DiXmlParseFailureException: Look! Read the message below.

	<component name="fessConfig" class="org.codelibs.fess.mylasta.direction.FessConfig$SimpleImpl"/>
</components>

Seems ok with xmllint and vanilla from lastest sources.

I have tried to understand what’s is going on but so far I have not any trail.

Could you put all stacktraces from logs?

Thanks. Reproduced. Fess does not seem to work on J9.

To run on J9, a workaround is:

cp -r lib/classes/javax app/WEB-INF/env/crawler/resources/
cp -r lib/classes/javax app/WEB-INF/env/thumbnail/resources/
cp -r lib/classes/javax app/WEB-INF/env/suggest/resources/

Hello,

Thank you for the workaround. I will test it ASAP.

FESS is working perfectly so far (including a test crawl) with openjdk-8-jre but not with openjdk-9-jre.
