    [ https://issues.apache.org/jira/browse/KARAF-2562?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13819872#comment-13819872

Achim Nierbeck commented on KARAF-2562:
---------------------------------------

This is a followup-issue, the main issue is the fact that ASM 4.1 used by Karaf doesn't work
with Java 8.
