[jira] [Commented] (OAK-1566) ArrayIndexOutOfBoundsException in Segment.getRefId()

    [ https://issues.apache.org/jira/browse/OAK-1566?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13942150#comment-13942150 ] 

Jukka Zitting commented on OAK-1566:
------------------------------------

This is probably related to the HAMT data structure used for child node entries, as the problem only seems to occur in cases where we're dealing with flat nodes with at least hundreds of thousands of children.

> It looks like there is some SegmentMK bug that causes the {{Segment.getRefId()}} to throw an {{ArrayIndexOutOfBoundsException}} in some fairly rare corner cases.
