We have an application where poi reads in an excel file using version 2.5.1 final. Everything works fine (except for the known bugs like comments). When we try to read in the same excel file with auto filter set to true, poi throws an unknownRecordFormat exception. This still worked in the previous version we were testing with (poi v2.0 Final)
Could you possibly attach the file?

This should be fixed with the patch that I applied for 27929. Checkout of HEAD and give it a shot.
