[jira] [Commented] (KARAF-3067) NoClassDefFoundError on startup
when log4j SMTPAppender is configured
[ https://issues.apache.org/jira/browse/KARAF-3067?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14043393#comment-14043393 ]
Jochen Kraushaar commented on KARAF-3067:
-----------------------------------------
Problem can be solved by installing feature jetty. If feature is installed as boot feature (in etc/org.apache.karaf.features.cfg), e.g. in custom distributions, exception occurs only on first startup - which is still annoying if you want to use a custom distribution as installation package on test or production systems.
