Subject [jira] Created: (SOLR-1917) Possible Null Pointer Exception in highlight or debug component
Date Mon, 17 May 2010 23:50:47 GMT
Possible Null Pointer Exception in highlight or debug component
---------------------------------------------------------------

                 Key: SOLR-1917
                 URL: https://issues.apache.org/jira/browse/SOLR-1917
             Project: Solr
          Issue Type: Bug
          Components: highlighter
    Affects Versions: 1.4
            Reporter: David Bowen


This bug may only show up if you have the patch for SOLR-1143 installed, but it should be
fixed in any case since the existing logic is wrong.  It is explicitly looking for the nulls
that can cause the exception, but only after the exception would have already happened.

What happens is that there is an array of Map.Entry objects which is converted into a SimpleOrderedMap,
and then there is a method that iterates over the SimpleOrderedMap looking for null names.
 That's wrong because it is the array elements themselves which can be null, so constructing
the SimpleOrderedMap throws an NPE.

I will attach a patch.
