Hi,
the first attempt to start fuseki as a web application within a Docker
with Apache, Tomcat and Elasticsearch images succeded.
But after a restart (i.e. docker-compose down/up) it failed with
'Illegal access' error. Moreover a reboot didn't help, the error still
occurs.
Do you have any idea wheater is this related to fuseki or not? As well
any clue how to fix it?
It looks like it is from ElasticSearch.
just kill the tomcat or container - graceful shutdown is a nicety and
any systems has to survive a non-graceful shutdown.

Thank you in advance
