The problem is the same for the following versions:
mysql-connector-java-5.0.4-bin.jar
mysql-connector-java-3.1.14-bin.jar
mysql-connector-java-3.1.8-bin.jar
mysql-connector-java-3.0.15-ga-bin.jar
I've checked with debugger - attribute's value is presented with NSData in
__dictionary property of EOEnterpriseObject. And it should've been converted
with "fromBlob" before getting there.
