Mike, You were right. As I have many indexes I keep a cache of the IndexWriters, and in some specific case (that cannot happen in my dev env) I was closing them without removing them from the cache. Somehow it was working before 2.1, and upgrading made the error clear.

One thing that changed in 2.1 is when a RAMDirectory is closed it now sets fileMap to null (which it did not pre-2.1). Is it possible you are accidentally closing a writer but then calling its addDocument method?
