    [ https://issues.jboss.org/browse/JASSIST-229?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12986668#comment-12986668 ] 

Johannes Rost commented on JASSIST-229:
---------------------------------------

The Issue is/was caused by a Java Agent of a monitoring tool (Introscope Wily) which was installed in a version that generates Java-6-bytecode. Deactivating this tool makes the errors disapear, so I'm closing this ticket. Please excuse any inconvenience caused.
