From: Dan Rollo Date: Wed, 7 Apr 2010 02:14:41 +0000 (+0000) Subject: Detect unsupported Jet and File formats and throw specific exceptions early. X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=refs%2Fheads%2Fnewformats;p=jackcess.git Detect unsupported Jet and File formats and throw specific exceptions early.
