This happens after changing the last updated timestamp of the '/etc/jetty8/contexts/eubon-utis-1.3.xml'

doing a

 rm /var/lib/utis/1.3/neo4j/eunis/store_lock

does not help, after removing the lock file the webapp restart still fails but with another exception:

java.lang.IllegalStateException: Unable to lock store [/var/lib/utis/1.3/neo4j/eunis/neostore.relationshiptypestore.db.names], this is usually caused by another Neo4j kernel already running in this JVM for this particular store
