Hello, Solr uses IndexCommit#getFileNames() to get a list of files for replication. One windows user reported an exception which looks like it may have been caused by IndexCommit#getFileNames() returning duplicate file names. The exception in his case was caused by "_21e.tvx" coming more than once.
The problem was reported to be fixed after we used new HashSet<String>(commit.getFileNames()). I haven't been able to reproduce the bug but I was hoping people here would know more about this. Solr is using the 2.9-dev version. Unfortunately, I don't know which revision that user was using. However if it is of any help, it should be one of r707499, r719351, r723985 or r724059.
