> This caused an npe from the ht.top().score lateron. 
> The root cause was a bug in a test case, which took 
> more time to track down than would have been necessary 
> with the attached patch. 
> The patch throws an IllegalArgumentException for non positive nDocs. 
> All current tests pass with the patch applied.
