java.lang.ClassNotFoundException: org.jledit.ConcreteEditorFactory

After quick fixing (https://issues.apache.org/jira/browse/KARAF-4704), we get a new issue:

/opt/apache-karaf/bin/shell wrapper:install
Exception in thread "main" java.lang.ClassNotFoundException: org.jledit.ConcreteEditorFactory

The source seems to be "KARAF-4570 Upgrade to JLine 3": https://github.com/apache/karaf/commit/8f813cf934e40ce2c9ab3b6b7257220ff91c0e7a.

The file "shell/commands/src/main/resources/META-INF/services/org/apache/karaf/shell" contains the line "org.jledit.ConcreteEditorFactory", but jledit seems to be obsolete. Must this line be replaced or can it be deleted completely?
