That is strange. If you turn off autowarming for fieldValueCache and this goes away that would be _really_ strange indeed.
But my bet is that you _are_ doing something that uninverts the text field (obviously inadvertently). If you restart Solr and monitor the log until the first time you see this exception, what do the queries show? My guess is that once you get some query in your queryResultCache or filterCache it gets recycled and produces this on autowarm rather than the fieldValueCache, but that's a total guess. And my guess is correct, there's probably _is_ a JIRA here to not put anything in caches (filter or queryResult) that's an exception......
