You could extend IndexWriter to AutoCommitIndexWriter and override flush() to call super.flush() then commit() (or simply just commit()). I haven't tested it but I think it should work.
However, make sure you understand the implications of commit() -- it's heavier than just flush. Perhaps you can avoid calling commit() frequently, and use NRT to obtain a fresh IndexReader over the flushed yet uncommitted data. If you don't want to periodically reopen that reader, then you could check after every addDocument if the IW RAM size has decreased (which indicates flush occurred), or move to use flush-by-doc-count and reopen every maxBufferedDocs. Hope this helps.
