--------------------------------------------

Can you capture IW.setInfoStream output leading up to it?

> I'm seeing the following exception during indexing:
> {code}
> Caused by: java.lang.ArrayIndexOutOfBoundsException: 14

> {code}
> This seems to be caused by the following code:
> {code}
>     final int level = slice[upto] & 15;
>     final int newLevel = nextLevelArray[level];
>     final int newSize = levelSizeArray[newLevel];
> {code}
> this can result in "level" being a value between 0 and 14
> the array nextLevelArray is only of size 10
> i suspect the solution would be to either max the level to 10, or to add more entries to the nextLevelArray so it has 15 entries
> however, i don't know if something more is going wrong here and this is just where the exception hits from a deeper issue
