I've created a hibernate query that returns a List. I can see the returned size of this list to be 100 items. When I try to iterate over this, I get the following exception:

java.lang.ArrayIndexOutOfBoundsException: -1


Not sure what the issue is here. Below is the snippet of my code:



I get the ArrayIndexOutOfBoundsException at the beginning of the for-loop. I checked that the returned List<Book> had the size of 100, so I know there are books in that List.

Any suggestions on how to troubleshoot and fix this? Thanks.

I'm able to drill down this problem a little further. I think the ArrayIndexOutOfBounds issue has to do with the index column to designate the position of the record in the List semantic, i.e. @IndexColumn(name = "position", base = 1). I've just added this type of column in a few tables that already exist with data. The column is designated as not null, and hence all of the existing data has their values set to 0. Any new records added will either be 1 or greater. My gut tells me that this scenario may be causing the ArrayIndexOutOfBounds issue I'm getting, since the base = 1, and it grabs data with base = 0. When I changed to base = 0 in my annotations, I get the same issue regardless. Any further ideas on this? Thanks.
