Yonik Seeley commented on SOLR-2861:
------------------------------------
Here's the fail5.xml analysis (more debugging prints this run):
{code}

2480 TEST:WRITER6: deleting id 0 val= 8 DONE
2491 VERBOSE:WRITER3: reopen DONE: searcher= Searcher@2aa937cd

DirectoryReader(segments_4:1319924531751:nrt _4(4.0):C13/8)
### Note that the delete happened sometime during (or right before or after)
the reopen, so we don't know if version 1319924531751 reflects the delete.
That's OK, because we are going to do another reopen next:
2516 VERBOSE:WRITER6: commit reopen start: reopenWithWriter= true searcher=
Searcher@2aa937cd main{DirectoryReader(segments_4:1319924531751:nrt
_4(4.0):C13/8),version=1319924531751} reader=
DirectoryReader(segments_4:1319924531751:nrt _4(4.0):C13/8)
2518 VERBOSE:WRITER6: reopen DONE: searcher= Searcher@59c958af
main{DirectoryReader(segments_4:1319924531751:nrt
_4(4.0):C13/8),version=1319924531751} reader=
DirectoryReader(segments_4:1319924531751:nrt _4(4.0):C13/8)
### OK... so the reopen didn't change the reader. That's OK, since there
weren't necessarily any new
changes (i.e. the delete of 0 could be reflected in the previous reopen).
2529 VERBOSE:READER18: RealTimeGet using searcher Searcher@59c958af
main{DirectoryReader(segments_4:1319924531751:nrt
_4(4.0):C13/8),version=1319924531751}
2531 TEST:READER18: ERROR, id= 0 foundVal= 7 model val= -8 realTime= true
#### Oops, we've found the old value again somehow.
{code}
Starting to look more like a lucene bug - but still can't reproduce at that
level.
