How to get rid of the exception "javax.jcr.PathNotFoundException: aa.bb.cc" ?

Issue

• We have suddenly started facing some issues like the metadata tab suddenly disappeared. So we deleted some database tables (e.g. FS_FSENTRY, VERSIONING_FS_FSENTRY, VERSIONING_PM_BINVAL, VERSIONING_PM_NODE, VERSIONING_PM_PROP, VERSIONING_PM_REFS) and the repository and data directories from the $JBOSS_HOME/bin directory, restarted the server and then imported the rules into the new server.

But still we are facing the following exception during server start-up. Can you please advice us how to solve this issue?
