Subject [jira] Commented: (LUCENE-2327) IndexOutOfBoundsException in
Date Thu, 18 Mar 2010 14:03:27 GMT


Shane commented on LUCENE-2327:

The index is relatively old and doesn't appear to have been modified for a number of years.
 I can't say for certain about prior exceptions.  If the CheckIndex results provides any more
details, then great.  Regardless, I'm willing to chalk this up to a system specific error
and close the ticket.  I was able to fix the index using Luke.

> The error is caused when the fieldNumber passed to FieldInfos.fieldInfo() is greater
than the size of array list containing the FieldInfo values.  I am not sure what the field
number represents or why it would be larger than the array list's size.  The quick fix would
be to validate the bounds but there may be a bigger underlying problem.  The issue does appear
to be directly related to LUCENE-939.  I've only been able to duplicate this in my production
environment and so can't give a good test case.
