             Summary: BKDReader exceptions at merge from innocuous? test
                 Key: LUCENE-7083
                 URL: https://issues.apache.org/jira/browse/LUCENE-7083
             Project: Lucene - Core
          Issue Type: Bug
            Reporter: Robert Muir


As part of LUCENE-7075, I tried to move join/ modules numeric join support away from deprecated encodings.

Basically from what i see, its encoding Numeric/SortedNumeric in a byte[] as an impl detail, it might as well use the new 8-bit encoding rather than the 7-bit one.

There are certain bugs in what i did, but i don't like the exceptions I see:

What is happening here? Is the exception correct or are we missing a check?
