[jira] [Commented] (OAK-7082) ArrayIndexOutOfBoundsException when upgrading from Oak 1.6

["Michael Dürig (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OAK-7082?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16297057#comment-16297057 ] 

Michael Dürig commented on OAK-7082:
------------------------------------

This is caused by {{GCJournal}} only taking care of the {{gc full generation}} field that was added to the {{gc.log}} in 1.8 but forgets to also take care of {{root id}}, which was also added with Oak 1.8.
